- integrations/django/middleware.py: do not pass get_response to super().__init__

 - SentryWrappingMiddleware: revert debugging hack, set new django_supports_async_middleware = DJANGO_VERSION >= (3, 1), use for both _asgi_middleware_mixin_factory and the async_capable flag inside SentryWrappingMiddleware

 - integrations/django/middleware.py: black autoformat

 - integrations/django/middleware.py: use all caps for capability variable

 - sentry_sdk/integrations/django/middleware.py: annotate stub _asgi_middleware_mixin_factory to match the .asgi typing
