Describe the bug
Django raises the deprecation warning shown below.

Exception & Traceback
RemovedInDjango41Warning: 'django_select2' defines default_app_config = 'django_select2.apps.Select2AppConfig'. Django now detects this configuration automatically. You can remove default_app_config.

Code Snippet
python -Wa manage.py check in a Django 3.2.8 project with django_select2 7.7.3 installed.

I assume this would be a breaking change - I'm not sure how far back Django stopped requiring explicit default_app_config definition.
