context menu: Improve docs aside responsiveness (#25347)

Closes https://github.com/zed-industries/zed/issues/24883

While this PR closes the issue above, it still doesn't implement a
bullet-proof solution for the context menu docs aside, meaning, it might
not work the best way if there are other places using it (like the
Editor Controls menu). For that, I think we'll want a more robust
collision-aware solution, possibly similar to the LSP completion menu.

Release Notes:

- N/A
