[Content]: Remove `default_app_config` suggestion for django docs

[nbhargava]

What article on segment.com/docs is affected?

https://segment.com/docs/connections/sources/catalog/libraries/server/python/#django

What part(s) of the article would you like to see updated?

This part of the article suggests that we should set default_app_config, but this feature will be removed in Django 4.1, and yields the following warning when included:

/usr/local/lib/python3.9/site-packages/django/apps/registry.py:91: RemovedInDjango41Warning: 'myapp' defines default_app_config = 'myapp.apps.MyAppConfig'. Django now detects this configuration automatically. You can remove default_app_config.
