## Summary
from https://github.com/astral-sh/ruff/pull/17034#discussion_r2024222525
This is a simple PR to fix the invalid behavior of `NotImplemented` on
Python >=3.10.
## Test Plan
I think it would be better if we could run mdtest across multiple Python
versions in GitHub Actions.
<!-- How was it tested? -->
