Prevent text from wrapping in code actions menu (#9178)

Antonio Scandurra created 

Right now we're basing the width of the menu on the longest code action
title. That is only an approximation and doesn't always coincide
perfectly with the true, longest code action.

Given that it's pretty close, however, this commit simply disables text
wrapping on the code action menu.

Release Notes:

- Fixed a rendering glitch that could cause code actions to not display
correctly ([#8341](https://github.com/zed-industries/zed/issues/8341))
