Update django-taggit to 5.0.0

[pyup-bot]

This PR updates django-taggit from 3.1.0 to 5.0.0.

Changelog

5.0.0

~~~~~~~~~~~~~~~~~~
* **Backwards icompatible:** Rename the (``content_type``, ``object_id``) index on ``TaggedItem``.
It is very unlikely for this to affect your code itself, and a migration will rename the index. This should not cause any downtime according to my research (Postgres does not lock the table for index renames, and Oracle holds a tiny lock to do it, and the change is only to the metadata, so is not dependent on table size).

* **Backwards incompatible:** Remove the ``.indexed_together`` and ``.unique_together`` attributes on ``TaggedItem``

We are instead using ``constraints`` and ``indexes`` to set up these properties.
* Remove support for Django 3.2.
* Remove usage of deprecated APIs for Django 4.2
* Remove support for Python 3.7 (no code changes involved)
* Fix ``tag_kwargs`` and ``TAGGIT_CASE_INSENSITIVE=True`` discrepency.

4.0.0

~~~~~~~~~~~~~~~~~~
* Remove Python 3.6 support (no code changes occurred, but we no longer test this release).
* Remove Django 4.0 support (no code changes occurred, but we no longer test this release).
* Add Django 4.2 support.
