Add language server version in a tooltip on language server hover (#45302)

I wanted a way to make it easy to figure out which version of a language
server Zed is running. Now, you get a tooltip when hovering on a
language server in the Language Servers popover.

This PR also fixes a bug. We had existing code to open a tooltip on
these language server entrees and display the language server message,
which was never fully wired up for `CustomEntry`s. Now, in this PR, we
will show show either version, message, or both, in the documentation
aside, depending on what the server has given us.

Mostly done with Droid (using GPT-5.2), with manual review and multiple
follow ups to guide it into using existing patterns in the codebase,
when it did something abnormal.

Release Notes:

- Added language server version in a tooltip on language server hover
