Let's try `django-stubs`

Probably it should work even without our mypy plugin. At least our CI check passes without it: https://github.com/typeddjango/django-stubs/blob/master/.pre-commit-config.yaml#L38-L53

P.S. why don't we use pip install -r requirements? Why all deps are copied?

why don't we use pip install -r requirements?

No great reason:

• I was hoping at some point to restore the ability for typeshed to see the impact of changes to third party stubs, in which case have the stub dependencies listed out statically would help
• At the time I updated these projects for modular typeshed, many did not have stubs dependences listed in a requirements file (e.g. only installed type stubs in CI or tox). I dislike mypy --install-types
• Some projects have a million dependencies that take forever to install

Looks like this doesn't work:
