CI tests use a fork of django: https://github.com/c24t/django/tree/spanner/stable/2.2.x. This fork includes many changes required to run the django tests with spanner. See the full list here.

Decide how to handle this fork long term, and ensure that it's up to date with the most-recently released version of django (for each version we support). Check that we still need these patches after fast-forwarding the underlying django branch in #598.

Was previously:

The CI build script is using @timgraham's fork of django:

It looks like this was added in 27222a3, but I can't tell why we needed to use this instead of django/django. Maybe because @timgraham merged a fix on his fork before it it was available on main?

In any case we should remove this now if we can. Related to the test cleanup work in #471.
