Reverts zed-industries/zed#3049

- Clicking on a channel name now joins the channel if you are not in it
- (or opens the notes if you are already there).
- When joining a channel, previously shared projects are opened
  automatically.
- If there are no previously shared projects, the notes are opened.

Release Notes:

- show host in the titlebar of shared projects
- clicking on faces in the titlebar will now always follow the person
(it used to toggle)
- clicking on someone in the channel panel will follow that person
- highlight the currently open project in the channel panel

- fixes a bug where sometimes following between workspaces would not
work

Release Notes:

- N/A

Otherwise the spawn to resolve the additional edits never runs causing
autocomplete to never add imports automatically when clicking with the
mouse

Release Notes:

- Fixed auto-complete additional edits, such as auto-import, not
applying when selecting a completion with a mouse click.

Before this change if you joined a project without clicking on the
notification it would never disappear.

Fix a related bug where if you have more than one monitor, the
notification was only dismissed from one of them.

Allows me to test notifications

An user complained in zed-industries/community#2093 that we always link
to the latest release changelog, not the one that they've just updated
to.


Release Notes:
- Fixed changelog link in update notification always leading to the
latest release changelog, not the one that was updated to. Fixes
zed-industries/community#2093.

The goal of this PR is to make Following more intuitive.

### Old Behavior

Previously, following was scoped to a project. In order to follow
someone in a given window, the window needed to contain a shared
project, and the leader needed to be present in the project. Otherwise,
following failed.

### New Behavior

* You can always follow **any** participant in the current call, in any
pane of any window.
* When following someone in a project that you're both collaborating in,
it works the same as before.
* When following someone in an unshared project, or a project that they
don't have open, you'll only get updates about the leader's views that
don't belong to a project, such as channel notes views. When the leader
focuses a file in a different project, you'll get the "follow $LEADER to
their active project" indicator

### Todo

* [x] Change db schema and RPC protocol so a project id isn't required
for following
* [x] Change client to allow following into non-project items regardless
of the leader's project
* [x] Assign colors to users in a way that doesn't require users to be
in a shared project.

This PR is a bit of a last minute change, but I realized there was
actually a third player in the Elixir LSP space who wants support as
well,
[lexical](https://github.com/zed-industries/community/issues/1567). I
realized that the settings arrangement I shipped in this preview
precludes adding a third kind of LSP. I don't have the time to learn how
to fully support this LSP, but I thought I'd at least refactor how the
settings are represented before this hits stable.

Release Notes:

- Changed the new `"elixir": { "next": "on" }` setting to `"elixir": {
"lsp": "next_ls" }`. The `elixir.lsp` setting requires a full restart to
take effect. (Preview only)

This makes zed always behave as if the app is active, even if no window is focused.
It prevents the 'viewing a window outside of zed' state during collaboration.

Release Notes:

- vim: Fix a bug where following could put you in visual mode

Release Notes:

- Fixed a bug in Zed's LSP implementation when using Next LS.
