False positive error when type(None) or NoneType is used as second argument to issubclass

[erictraut]

Pyright shouldn't generate an error when type(None) or NoneType is used in the second argument to issubclass.

issubclass(int, type(None))

Furthermore, this should work for type narrowing, but it doesn't currently.

def func(x: type[None] | type[int]):
    if issubclass(x, type(None)):
        reveal_type(x, expected_text="type[None]")
    else:
        reveal_type(x, expected_text="type[int]")

This is related to a bug filed in the mypy issue tracker: python/mypy#16279

This is included in pyright 1.1.332, which I just published. It will also be included in a future release of pylance.
