Fix warning RemovedInDjango41Warning

[gitenth]

Please fix warning:

RemovedInDjango41Warning: 'massadmin' defines default_app_config = 'massadmin.apps.MassAdminConfig'. Django now detects this configuration automatically. You can remove default_app_config. app_config = AppConfig.create(entry)

add code into massadmin/__init__.py:

import django

if django.VERSION < (3, 2):
    default_app_config = 'massadmin.apps.MassAdminConfig'

@gitenth Could you please convert your comment into Pull request?

@gitenth I have released django-mass-edit version 3.5.0 which should support Django up to 4.2.
Is this issue still a problem in that version?

Yes, it looks like it's still an issue with v3.5.0. I see the warning when I run Django with warnings enabled:

PYTHONWARNINGS=default python manage.py runserver
