Cannot override a class's callable variable with a method

[Jesse205]

Describe the bug

When a base class has a Callable variable without a Self parameter, overriding this variable in a subclass causes an error, which is inconsistent with the behavior of mypy and ty.

Code or Screenshots

from collections.abc import Callable
from typing import override


class A:
    hello: Callable[[], None] = lambda: print("hello")


class B(A):
    @override
    def hello(self) -> None:
        print("hi")


b = B()
b.hello()
# Output: hi
