Django 3.2 introduced `DEFAULT_AUTO_FIELD = 'django.db.models.AutoField'`.
However, if we set it to BigAutoField, I would expect that the
intermediary table created for ManyToMany relationships also honor this
value.
Right now, we end up with tables that have FKs as bigint, but their own PK
as integer. This may not be a direct bug, but will cause issues for sure.
Ideally, ManyToManyField should have an easy way to configure its PK
without having to implement the `through` model.
