Describe the bug / provide steps to reproduce it

When you delete the files with the errors, Zed should not display errors anymore.

Reproduce:

• Create a file with syntax error
• Make sure Zed detects it
• Delete the file and every occurrence
• Observe Zed still shows the errors

Environment

Zed: v0.73.3 (stable) OS: macOS 13.0.0 Memory: 64 GiB Architecture: aarch64

If applicable, add mockups / screenshots to help explain present your vision of the feature

If applicable, attach your ~/Library/Logs/Zed/Zed.log file to this issue.

If you only need the most recent lines, you can run the zed: open log command palette action to see the last 1000.

Nothing special

Note that same thing happens for warnings

I can't repro this with Rust project anymore (or a .js one).
