I think honestly PYI020 is a better fit for stub files and if TYPE_CHECKING blocks, so the logic here should probably be changed. But for now I'm just maintaining compatibility with previous versions of Ruff, which emitted this lint on annotations in stub files as well as annotations in .py files. Abruptly reducing the scope of the rule like that would maybe be slightly backwards-incompatible; it at least should be considered in a separate PR.

Can we a test for if there is code in an else block after the TYPE_CHECKING? That shouldn't be treated a stub, right?

Sure, I can add a test for that.

Summary
Fixes #11245.
if TYPE_CHECKINGblocks, like stub files, are never executed at runtime -- so I think it makes sense to give them stub-file semantics when it comes to whether forward references are or aren't permitted. Currently we allow forward references in stub files on the r.h.s. of type alias definitions and in class bases; this PR implements the same logic forif TYPE_CHECKINGblocks.Test Plan
cargo test/cargo insta review. Two fixtures have been extended.
