bulk_create "Self" Typing Error: Argument 1 to "bulk_create" of "Manager" has incompatible type "list[MyModel]"; expected "Iterable[Self]"

[Myselfito]

Bug report

The objects manager seems to be weirdly mistyping the required iterable for bulk_create.
A Self type is required (which is OK), but this Self type is conflicting with the class type.
See minimal reproduction below.

What's wrong

# models.py
from django.db import models

class MyModel(models.Model):
    pass
    
    @classmethod
    def test_bulk_create(cls) -> None:
        created = [cls()]
        cls.objects.bulk_create(created)  # error: Argument 1 to "bulk_create" of "Manager" has incompatible type "list[MyModel]"; expected "Iterable[Self]"  [arg-type]

How is that should be

The above code should not generate an error.

Using the "abstract model" mitigator _default_manager is working, but here the model is concrete (I tried with strict_model_abstract_attrs=false, which does not solve the issue).

The issue might be in the bounding of the objects attribute on subclasses (as it's deleted from the db/models/base.pyi Model stub).
