`ruff server`: Improve error message when a command is run on an unavailable document (#11823) ## Summary Fixes #11744. We now show a distinct popup message when we fail to get a document snapshot during command execution.

You should see the following popup message: <img width="456" alt="Screenshot 2024-06-11 at 11 47 16 AM" src="https://github.com/astral-sh/ruff/assets/19577865/3a28e3d7-3896-4dd0-b117-f87300dd3b68">
