This ticket should be "Someday/Maybe" until we start working on Django 5.0.

In 170b0a47:

Refs #34233 -- Used @staticmethod with TextChoices._generate_next_value_().

Now that Python 3.10 is the minimum supported version, we can decorate
_generate_next_value_() with @staticmethod. It wasn't possible before
as Python < 3.10 does not support calling static methods direct from
the class body.
