Error on Field.limit_choices_to with callable

[H4rryK4ne]

Bug report

What's wrong

I get a mypy error when I use a callable on a ForeignKey.limit_choices_to argument:

error: Argument "limit_choices_to" to "ForeignKey" has incompatible type "Callable[[], dict[str, set[Any]]]"; expected "Q | dict[str, Any] | _ChoicesCallable | None"  [arg-type]

My code looks like this:

def limit_to_procedures() -> dict[str, set[Any]]:
    return {"pk__in": {content_type.pk for content_type in ContentType.objects.get_for_models(*AbstractModel.__subclasses__()).values()}} 

def Foo(Model):
  content_type = ForeignKey(ContentType, limit_choices_to=limit_to_procedures, on_delete=CASCADE)

How is that should be

No error should be thrown.
