Fixes #7236.

The reason why the code was not displayed correctly is due to missing
background color for the inline code block.

alt="Screenshot showing that inline code blocks are now highlighted in

Release Notes:

- Fixed inline code block not shown in markdown preview
([#7236](https://github.com/zed-industries/zed/issues/7236)).

This changes the highlighting of Go code to make it more similar to how
we highlight Rust

* normal variables have the normal color, vs. being highlighted. This
really stuck out.
* brackets are properly highlighted

It also brings it closer to Neovim's tree-sitter highlighting by
changing how struct fields are highlighted.



Release Notes:

- Improved highlighting of Go code by tuning highlighting of variables,
brackets, and struct fields.

## Before & After

![screenshot-2024-02-02-11 38
08@2x](https://github.com/zed-industries/zed/assets/1185253/a754f166-89c1-40e8-a8da-b63155180896)

The way Rust generics works, having a generic argument puts the burden of codegen on the crate that instantiates a generic function, which in our case is an editor.

This changes the Go `outline.scm` queries a bit so that we don't have
these stray whitespaces floating around. I'm sure there's more
improvements possible, but for now I think this makes it look less
wrong.

Release Notes:

- Improved outline and breadcrumbs for Go code.

## Before

![before](https://github.com/zed-industries/zed/assets/1185253/d2b93c41-639b-4819-b87e-d8456960c5a7)

![after](https://github.com/zed-industries/zed/assets/1185253/1ff6efb1-75a4-487b-8947-f070073887d4)

This PR implements support for displaying diagnostics in the scrollbar,
similar to what is already done for search results, symbols, git diff,
...

For example, changing a field name (`text`) without changing the
references looks like this in `buffer.rs` (note the red lines in the
scrollbar):

![image](https://github.com/zed-industries/zed/assets/53836821/c46f0d55-32e3-4334-8ad7-66d1578d5725)

As you can see, the errors, warnings, ... are displayed in the scroll
bar, which helps to identify possible problems with the current file.

Relevant issues: #4866, #6819

Release Notes:

- Added diagnostic indicators to the scrollbar

This reverts commit 020c38a8916c063cba36c2c88a69b5e287269d5a because it
leads to glitches when selecting text.

After this change we'll be able to push a tag to github to deploy to
collab.

The advantages of this are that there's no longer a separate step to
first
build the image, and then deploy it.

In the future I'd like to make this happen more automatically (maybe as
part of
bump nightly).

This will introduce an extra conditional but saves us from doing a bunch
of math in the simple case of drawing simple rectangles that aren't
rounded or don't have borders.

This pull request implements support for the [Erlang
Language](https://erlang.org/).

**It adds:**

* [tree-sitter-erlang](https://github.com/WhatsApp/tree-sitter-erlang)
grammar
highlights (Licensed under Apache-2 from WhatsApp which is compatible
with Zed licensing model), folds and indents
* Erlang file icon based on the [official
one](https://www.erlang.org/doc/erlang-logo.png)
* [erlang_ls](https://github.com/erlang-ls/erlang_ls) support

Fixes https://github.com/zed-industries/zed/issues/4939, possibly a
duplicate of https://github.com/zed-industries/zed/pull/7085 with more
features. Suppose @wingyplus wants to join efforts here.

**To complete (out of scope for this PR):**

* Support for the ELP language server from WhatsApp. CC @robertoaloi
* Better indentation handling, need something like
`indentNextLinePattern` in VS Code

Previously we would run these loops indefinitely when a language server
closed its stdout/stderr and the `read_until` returned `0` bytes read.

Easy to reproduce: start Zed with LSP attached, `kill -9` the LSP, see
logs accumulate.

Release Notes:

- Fix high CPU usage when a language server crashes (or closes its
stdout/stderr on purpose).

Based on the great work in
https://github.com/zed-industries/zed/pull/7130 , now sends this data

    name: "Zed Dev",
    version: Some(
        "0.122.0",
    ),
}
```

with every LSP server initialization.

Release Notes:

- Added Zed name and version to LSP InitializeParams requests

This is a follow-up to #7141 and fixes the focus-switching to docks in
case they haven't been focused before.

We ran into issues when trying to focus a dock, that hasn't been focused
in the app's lifecycle: focus would only flip after the next re-render
(which could be triggered by moving the mouse, for example)

This changes the approach and uses the one we have for `toggle focus`
actions.

Just a small improvement as a follow up to @kierangilliam great work on
#6958

Rendering a table specified like this:
```markdown
| Left columns  | Center columns | Right columns |
| ------------- |:--------------:| -------------:|
| left foo      | center foo     | right foo     |
| left bar      | center bar     | right bar     |
| left baz      | center baz     | right baz     |
```
Does now look like this (notice the cell alignments):

Release Notes:

Follow-up of https://github.com/zed-industries/zed/pull/6947 (cc
@alygin) that fixes a few style nits and refactors the code around:
* use already stored `currently_opened_path` to decide what to do with
the history item sorting
* use the same method to set history items, encapsulate the bubbling up
logic there
* ensure history elements are properly sorted before populating

The main reason to change all that is the new comparator in the previous
version:
https://github.com/zed-industries/zed/pull/6947/files#diff-eac7c8c99856f77cee39117708cd1467fd5bbc8805da2564f851951638020842R234
that almost violated `util::extend_sorted` contract, requiring both
collections to be sorted the same way as the comparator would be: it did
work, because we bubbled currently open item up in the history items
list manually, and that we have only one such item.

Release Notes:
- N/A

This PR completes the first task of the Tabless editing feature (#6424).
It makes file finder select the previously opened file by default which
allows the user to quickly switch between two last opened files by
clicking `Cmd-P + Enter`.

This feature was also requested in #4663 comments.

Release Notes:
* Improved file finder selection: currently opened item is not selected now

This adds the ability to navigate to/from docks (Terminal, Project,
Collaboration, Assistant) via keybindings.

When using the `ActivatePaneInDirection` keybinding from the
left/bottom/right dock, we check whether the movement is towards the
center panel. If it is, we focus the last active pane.

Fixes https://github.com/zed-industries/zed/issues/6833 and it came up
in a few other tickes/discussions.

Release Notes:

- Added ability to navigate to docks and back to the editor using the
`workspace::ActivatePaneInDirection` action (by default bound to `Ctrl-w
[hjkl]` in Vim mode).
([#6833](https://github.com/zed-industries/zed/issues/6833)).

## Drawback

There's this weird behavior: if you start Zed and no files are opened,
you focus terminal, go left (project panel), then back to right to
terminal, the terminal isn't focused. Even though we focus it in the
code.

Maybe this is a bug in the current focus handling code?
