[Bug]: PEP 585 generic support mishandles primitive composites

[jrmccluskey]

What happened?

The support for PEP 585 generics added in #25054 missed removing the constraint on primitives in composites, leading to type hints like tuple[str, list] returning an error instead of being converted to Tuple[str, List[Any]].
