Display language server info in the server logs tab (#22797)

Follow-up of https://github.com/zed-industries/zed/pull/19448

When dealing with issues like
https://github.com/zed-industries/zed/issues/22749, it's quite tedious
to ask for logs and check them out.

This PR attempts to establish a single "diagnose my language server"
place in the server logs panel, where server capabilities were already
displayed after https://github.com/zed-industries/zed/pull/19448

The design is pretty brutal, but seems to be on par with the previous
version and it's a technical corner of Zed, so seems to be ok for now:

Release Notes:

- Improved lsp logs view to display more language server data
