[pycodestyle] Fix duplicated diagnostic in E712

[LaBatata101]

Summary

Fixes a duplicated diagnostic when both sides of the operator are True.
Example:

if True == True:
    ...

Let me know if there is another case where this could happen, I couldn't think of any.

Fixes #17582.

Test Plan

Snapshot tests.

[LaBatata101]

Hmm, weird tests didn't fail locally.

@LaBatata101 You probably changed the comment in E712.py and forgot to rerun cargo insta test afterwards or you forgot to include your updated snapshot in your initial commit.

It used to read # No duplicated error, but you changed it to # No duplicated diagnostic, but the snapshot still contains the old comment. The snapshot needs to match exactly, so every time you change the source code, you also need to update the snapshot again.
