Using UserAdmin with AbstractBaseUser

[Superpat]

Bug report

What's wrong

I cant use UserAdmin for a user that's based on AbstractBaseUser and I cant import BaseUserAdmin.

saskatoon/member/admin.py:50: error: Type argument "AuthUser" of "UserAdmin" must be a subtype of "AbstractUser"  [type-var]

ImportError: cannot import name 'BaseUserAdmin' from 'django.contrib.auth.admin' (/app/.tox/mypy/lib/python3.9/site-packages/django/contrib/auth/admin.py)

The class declaration is as such:

class AuthUserAdmin(UserAdmin[AuthUser]):

See https://github.com/LesFruitsDefendus/saskatoon-ng/blob/mypy_django/saskatoon/member/admin.py for the actual file.

How is that should be

I dont know what I'm supposed to do.
