Django <= 3.X defaults to using ZoneInfoBackend instead of PYTZBackend #109
Description
This is because without explicitly setting use_pytz=True in a TimeZoneField, use_pytz defaults to None, causing get_tz_backend to return ZoneInfoBackend instead of the intended PYTZBackend.
A workaround ahead of a code fix is to explicitly set use_pytz=True in a TimeZoneField.
