This PR contains various improvements for the markdown preview (some of
which were originally part of #7601).
Some improvements can be seen in the video (see also release notes down
below):

Release Notes:
- Added action to open markdown preview in the same pane
- Added support for displaying channel notes in markdown preview
- Added support for displaying the current active editor when opening
markdown preview
- Added support for scrolling the editor to the corresponding block when
double clicking an element in markdown preview
- Improved pane creation handling when opening markdown preview
- Fixed markdown preview displaying non-markdown files
Closes#5178
Release Notes:
- Added a `file_types` setting that can be used to associate languages
with file names and file extensions. For example, to interpret all `.c`
files as C++, and files called `MyLockFile` as TOML, add the following
to `settings.json`:
```json
{
"file_types": {
"C++": ["c"],
"TOML": ["MyLockFile"]
}
}
```
As with most zed settings, this can be configured on a per-directory
basis by including a local `.zed/settings.json` file in that directory.

This PR improves support for rendering markdown documents.

## Before the updates
https://github.com/zed-industries/zed/assets/18583882/6d7ddb55-41f7-492e-af12-6ab54559f612
## New features
- @SomeoneToIgnore's [scrolling feature
request](https://github.com/zed-industries/zed/pull/6958#pullrequestreview-1850458632).
- Checkboxes (`- [ ]` and `- [x]`)
- Inline code blocks.
- Ordered and unordered lists at an arbitrary depth.
- Block quotes that render nested content, like code blocks.
- Lists that render nested content, like code blocks.
- Block quotes that support variable heading sizes and the other
markdown features added
[here](https://github.com/zed-industries/zed/pull/6958).
- Users can see and click internal links (`[See the docs](./docs.md)`).
## Notable changes
- Removed dependency on `rich_text`.
- Added a new method for parsing markdown into renderable structs. This
method uses recursive descent so it can easily support more complex
markdown documents.
- Parsing does not happen for every call to
`MarkdownPreviewView::render` anymore.
## TODO
- [ ] Typing should move the markdown preview cursor.
## Future work under consideration
- If a title exists for a link, show it on hover.
- Images.
- Since this PR brings the most support for markdown, we can consolidate
`languages/markdown` and `rich_text` to use this new renderer. Note that
the updated inline text rendering method in this PR originated from
`langauges/markdown`.
- Syntax highlighting in code blocks.
- Footnote references.
- Inline HTML.
- Strikethrough support.
- Scrolling improvements:
- Handle automatic preview scrolling when multiple cursors are used in
the editor.
- > great to see that the render now respects editor's scrolls, but can
we also support the vice-versa (as syntax tree does it in Zed) — when
scrolling the render, it would be good to scroll the editor too
- > sometimes it's hard to understand where the "caret" on the render
is, so I wonder if we could go even further with its placement and place
it inside the text, as a regular caret? Maybe even support the
selections?
- > switching to another markdown tab does not change the rendered
contents and when I call the render command again, the screen gets
another split — I would rather prefer to have Zed's syntax tree
behavior: there's always a single panel that renders things for whatever
tab is active now. At least we should not split if there's already a
split, rather adding the new rendered tab there.
- > plaintext URLs could get a highlight and the click action
## Release Notes
- Improved support for markdown rendering.
