Subject: [PATCH] Re-drop dependency on `typing_extensions` (#269)

Since it was only being used for `TypedDict`, which was added in
Python 3.8 and `dj-database-url` v2.3.0+ only supports Python 3.9+.

See:
https://docs.python.org/3.12/library/typing.html#typing.TypedDict
https://github.com/jazzband/dj-database-url/blob/master/CHANGELOG.md#v230-2024-10-23

Note: This is a repeat of #257, since that PR was lost as part
of merges that occurred during the release of 3.0.0:
https://github.com/jazzband/dj-database-url/pull/257#issuecomment-3023857093
