## Summary Part of #8771. flake8-pyi will emit a Y018 error for unused TypeVars, ParamSpecs or TypeVarTuples; Ruff currently only emits PYI018 for unused TypeVars. This is my first "proper" Ruff PR -- let me know if there's a better way of doing this! Not sure if the repeated calls to `match_typing_expr()` are ideal. ## Test Plan I manually updated the fixtures to add some unused ParamSpecs and TypeVarTuples, and then updated the snapshots using `cargo insta review`. All tests then passed when run using `cargo test`.
