Formatting with Ruff Doesnt Work

[Notenlish]

Summary

Ruff formatter doesn't work. I've already installed the extension and configured it but it still doesn't work.

Description

Steps to reproduce:

1. add settings.json
2. Open a python file and tell zed to format it

Expected Behavior: Formatting works Actual Behavior: nothing happens

2. Check your Zed.log for relevant errors? (please include!)
3. Click Preview to ensure everything looks right?

Are you saying that to me? I don't think I can assign it to you, i dont have permissions for that

You're missing the formatter declaration telling us to use ruff for LSP formatting, instead of just code action formatting. Please add the following above in the "formatter" array for Python and @-mention me if that doesn't fix the issue for you so we can figure out what else may be going wrong

        {
          "language_server": {
            "name": "ruff"
          }
        }

It seems to be definitely working, thanks a lot!
