Ruff failing to start when used directly in notebook

[AWH1122]

When ruff is being used exclusively in a notebook it fails to start. Here is the log output:

2025-01-26 19:54:52.014 [info] Name: Ruff

[Option 1] Select Python interpreter using the ms-python.python.
[Option 2] Set an interpreter using "ruff.interpreter" setting.
Please use Python 3.7 or greater.

If I create a .py file, select and interpreter, then restart the language server it works.

Steps to Reproduce:

1. Open jupyter notebook
2. Try to format document and notice ruff is not working

Thanks for the report.

Unfortunately, I'm not sure if this is a bug in Ruff extension because we use the Python extension to query the currently selected Python interpreter (refer to the screenshot, in the toolbar it says "Select interpreter" which is coming from the Python extension as it's unable to determine it for the project). As mentioned in the logs, one of the ways to resolve this would to use the ruff.interpreter setting. We're also looking into improving the UX for this part especially for the native server because we could skip this step if the extension is unable to get a Python executable (#598).
