AnyClassMethod type annotation

[mehdigmira]

Initial Checks

• I have searched GitHub for a duplicate issue and I'm sure this is something new
• I have searched Google & StackOverflow for a solution and couldn't find anything
• I have read and followed the docs and still think this is a bug
• I am confident that the issue is with pydantic (not my code, or another library in the ecosystem like FastAPI or mypy)

Description

Hello, current type annotation for AnyClassMethod is classmethod[Any] while the definition in typeshed has changed
as you can see in https://github.com/python/typeshed/blob/main/stdlib/builtins.pyi#L131
This change has been introduced in typeshed a couple of weeks ago https://github.com/python/typeshed/pull/9771/files

Would it be possible to fix the type annotations in pydantic accordingly ?

This impact pyright, as it starts reporting "partially unknown" types (which it is right about)

Still relevant for pydantic==1.10.7. We are unable to use the last few releases of pyright until this is resolved.
