Update whitenoise to 6.5.0

[pyup-bot]

This PR updates whitenoise from 6.3.0 to 6.5.0.

Changelog

6.5.0

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

* Support Python 3.12.

* Changed documentation site URL from ``https://whitenoise.evans.io/`` to ``https://whitenoise.readthedocs.io/``.

6.4.0

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

* Support Django 4.2.

* Remove further support for byte strings from the ``root`` and ``prefix`` arguments to ``WhiteNoise``, and Django’s ``STATIC_ROOT`` setting.
Like in the previous release, this seems to be a remnant of Python 2 support.
Again, this change may be backwards incompatible for a small number of projects, but it’s unlikely.
Django does not support ``STATIC_ROOT`` being a byte string.
