Add migration due to noop FK from Django 4.0

[Andrew-Chen-Wang]

Description of the Change

I wanted to double check that 4.0.1 wouldn't create a new migration. Turns out, I missed a comment from the PR that mentions how a migration would still be created. The reason is because of the related_name using the placeholder itself now rather than using "oauth2_provider".

Fortunately, this migration isn't as drastic as the auth.User one which would have deleted data... Let me know if I'm missing anything else.

I'm marking this as a draft until I get a chance to dig in deeper to better understand the impact.

Unfortunately swappable models and migrations in DOT have always been a problem, with lots of manual tweaking of auto migrations required in the past. I've never completely understood the reasoning....

@Andrew-Chen-Wang I'm reading the PR commit django/django@4328970 and don't see where it says the new migration should be created....

Ah so it's in 4.0 release notes. The 4.0.1 thing talked about a different fix that you reported the bug for. Got it. So we'll have this noop migration....
