[pyup-bot]

This PR updates django-filter from 21.1 to 23.5.

Changelog

23.5

-------------------------

* Fixed OrderingFilter handling of empty values. (1628)

Thanks to Matt Munns.

23.4

-------------------------

* Official support for Django 5.0 and Python 3.12.

* Fix DeprecationWarning for pkgutil.find_loader.

Thanks to `wmorrell`.

* Adopted Furo theme for docs.

23.3

------------------------

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

* Updates packaging to use pyproject.toml and Flit.

23.2

------------------------

* 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``coreapi`` is no longer maintained, and is raising warnings against the current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.

23.1

------------------------

* 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)

22.1

------------------------

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

* Added testing for Python 3.10 and Django 4.1.

* Removed outdated deprecated warnings for code removed in version 2.1.

* Removed `filter_class` (use `filterset_class`) and `filter_fields`
(`filterset_fields`) that were deprecated in [version 2.0
(2018)](https://django-filter.readthedocs.io/en/main/guide/migration.html#view-attributes-renamed-867).

* The code base is now formatted with Black.
