Describe the feature

After yesterdays somewhat broken release of rust-analyzer (rust-lang/rust-analyzer#18854), which has now been fixed, it highlighted a maybe missing feature. Which would be to manually downgrade rust-analyzer version and perhaps even a toggle for auto-updating it, notification regarding rust-analyzer releases and updates?

Temporary workaround for the issue in question was to downgrade rust-analyzer, however with Zed it simply wasn't possible (at least not that we're aware of?).

•  Ability to downgrade rust-analyzer version
• Ability to toggle auto-updates for rust-analyzer
• rust-analyzer update notifications (if auto-update is not toggled on).

Thank you.

You could configure rust-analyzer to use a binary on your machine, for example.

{
  "lsp": {
    "rust-analyzer": {
      "binary": {
        "ignore_system_version": false,
      }
    }
  }
}

That would try to find rust-analyzer in $PATH.

Or you specify the path manually:

{
  "lsp": {
    "rust-analyzer": {
      "binary": {
        "path": "/Users/foobar/bin/rust-analyzer,
      }
    }
  }
}

I think that's a simpler workaround here than providing version management/selection in side Zed.

While I do agree this might be a simpler workaround, the fact that Zed by default downloads the latest rust-analyzer release, I think that if this happens again in the future, people won't be really happy for having to manually download and modify Zeds configuration, just to change it again back once the fix is released.

Especially since it adds complexity to managing something that the editor relies on and should already be built into the IDE itself (imo).
