This PR updates the `theme_importer` to use `serde_json_lenient` to
parse VS Code themes.

This should allow us to parse themes that have trailing commas and such,
in addition to the comment support that we already had.

This change switches from using async_tungstenite::async_tls to
async_tungstenite::async_std with the async-native-tls feature.

The previous feature, async_tls, used async-tls which wraps rustls.
rustls bundles webpki-roots, which is a copy of Mozilla's root
certificates. These certificates are used by default, and manual
configuration is required to support custom certificates, such as those
required by web security gateways in enterprise environments.

Instead of introducing a new configuration option to Zed,
async-native-tls integrates with the platform-native certificate store
to support enterprise environments out-of-the-box. For MacOS, this adds
support for Security.framework TLS. This integration is provided through
openssl-sys, which is also the SSL certificate provider for isahc, the
library underlying Zed's HTTP client. Making websockets and HTTP
communications use the same SSL provider should keep Zed consistent
operations and make the project easier to maintain.



Release Notes:

- Fixed WebSocket communications using custom TLS certificates
([#4759](https://github.com/zed-industries/zed/issues/4759)).

This fixes a panic happening when releasing an instance buffer.
Releasing the buffer happens on a different thread but the borrow
checker was not catching it because the metal buffer completion handler
API doesn't have a `Send` marker on it.

Release Notes:

- N/A

This change makes it so that if you are the first to join a channel,
your project is automatically shared.

It also makes it so that if you join a channel via a link and there are
no shared projects, you open the notes instead of an empty workspace
with nothing.

This is to try and address the discoverability of project sharing: we've
had
two reviews that have talked about channels, but not talked about
sharing
projects into them, which makes me suspect they didn't know about the
feature.

Release Notes:

- Added a setting `share_on_join` (defaulting to true). When set, and
you join an empty channel, your project is automatically shared.

I keep seeing people leave the wrapping parentheses, like `(Added)` in
their release notes.

This PR tries making it clearer that we only want *one* of "Added",
"Fixed", or "Improved".

Release Notes:

- N/A

This commit goes back to using `wait_until_scheduled` as opposed to
`wait_until_completed`. What this means, however, is that another draw
could take place before the previous one finished. When that happens we
don't want to reuse the same instance buffer because the GPU is actively
reading from it, so we use a pool instead.

Release Notes:

- Fixed a bug that caused inconsistent frame rate when scrolling on
certain hardware.

Fixes the padding of the "notes" button in collab-ui. I'm not sure why
the previous code used `div().h_7().w_full()`. Am I missing something
here?

This adds four new actions:

- `editor::MoveUpByLines`
- `editor::MoveDownByLines`
- `editor::SelectUpByLines`
- `editor::SelectDownByLines`

They all take a count by which to move the cursor up and down.
(Requested by Adam here:
https://twitter.com/adamwathan/status/1753017094248018302)


Example `keymap.json` entries:

```json
{
  "context": "Editor",
  "bindings": [
    "alt-up":         [ "editor::MoveUpByLines",     { "lines": 3 } ],
    "alt-down":       [ "editor::MoveDownByLines",   { "lines": 3 } ],
    "alt-shift-up":   [ "editor::SelectUpByLines",   { "lines": 3 } ],
    "alt-shift-down": [ "editor::SelectDownByLines", { "lines": 3 } ]
  ]
}
```

They are *not* bound by default, so as to not conflict with the
`alt-up/down` bindings that already exist.

Release Notes:

- Added four new actions: `editor::MoveUpByLines`,
`editor::MoveDownByLines`, `editor::SelectUpByLines`,
`editor::SelectDownByLines` that can take a line count configuration and
move the cursor up by the count.

I ran into this a lot with Go code: the documentation would be empty so
we'd display a big box with nothing in it.

I think it's better if we only display the box if we have documentation.

Release Notes:

- Fixed documentation box in showing up when using auto-complete even if
documentation was empty.

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
Markdown preview">



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.

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.

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.
