project: Fix organize imports action not working for Python (#45874)

Closes https://github.com/zed-industries/zed/issues/26819

Explained in
https://github.com/zed-industries/zed/issues/26819#issuecomment-3399175027
That action is now the default on format in
https://github.com/zed-industries/zed/pull/41103 since October, but
applying manually is still broken.

Release Notes:

- Fixed an issue where the `editor: organize imports` action didn’t work
for Python, even though imports were organized correctly during
formatting.
