In most languages, Zed will check 2-3 locations for language servers.
For instance, when opening a python file, zed looks for ruff in:

- project venv
- user's PATH
- location that zed installs language servers

The language server menu surfaces information that makes it easier to
gather data about your language server, I think offering a path for the
one being ran makes things more clear to the user.

That being said, Idk the best way to surface this. (@danilo-leal?)

Release Notes:

- Add language server path to a tooltip that is produced when hovering
on its status in the language server menu
