`isinstance(..., abc.Callable)` not supported

[randolf-scholz]

Describe the Bug

from collections.abc import Callable

assert isinstance(len, Callable)  # E: Expected class object, got `type[Callable]`

Python: 3.12

This is supported at runtime and by other type checkers, and more or less equivalent to callable(...). cpython source
