Update django-filter requirement from ==2.4.* to ==23.4 in /requirements

[dependabot[bot]]

Updates the requirements on django-filter to permit the latest version.

Changelog

Sourced from django-filter's changelog.

Version 23.4 (2023-11-20)

• Official support for Django 5.0 and Python 3.12.

• Fix DeprecationWarning for pkgutil.find_loader.

  Thanks to wmorrell.

• Adopted Furo theme for docs.

Version 23.3 (2023-9-17)

• Adds initial compatibility with Django 5.0, prior to Django 5.0a1.

• Updates packaging to use pyproject.toml and Flit.

Version 23.2 (2023-4-30)

• Deprecated the schema generation methods of the DRF related DjangoFilterBackend. These will be removed in version 25.1.

  You should use drf-spectacular <https://drf-spectacular.readthedocs.io/en/latest/>_ for generating OpenAPI schemas with DRF.

• In addition, stopped testing against the (very old now) coreapi schema generation. These methods should continue to work if you're using them until v25.1, but coreapi is no longer maintained, and is raising warnings against the current versions of Python. To workaround this is not worth the effort at this point.

• Updated Polish translations.

Version 23.1 (2023-3-26)

• Declared support for Django 4.2.

• Various updated and new translations. Thanks to all who contributed, and Weblate for hosting.

• Fixed QueryArrayWidget.value_from_datadict() to not mutate input data. (#1540)

Version 22.1 (2022-6-17)

• Update supported Python and Django versions: minimal Python is now 3.7, minimum Django is now 3.2.
