We use the library django-stubs pretty extensively. Recently, they
introduced a patch treating more types as Generics. To handle this on our
side we either need to work `mypy` in a decently annoying manner. Much
like issue #31223, I propose we add a `__class_getitem__` to the following
classes:
* BaseModelAdmin
* Options
* Lookup
* Field
Much like before `__class_getitem__` would purely be for `mypy` type
checks and a no-op for the django runtime. Only other thing to note, for
us the most important class to update would be `BaseModelAdmin`, so if
there are reasons not to add `__class_getitem__` to the other classes, I
can forgo that change.
