[deps] Update django-taggit requirement from ~=4.0.0 to ~=6.0.0

[dependabot]

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

Changelog

Sourced from django-taggit's changelog.

5.0.1 (2023-10-26)

• Fix the package metadata to properly reflect the right Django and Python version requirements Release 5.0.0 improperly stated its Django bounds as >=3.2, so people installing without bounds will end up on a version that won't work.

5.0.0 (2023-10-24)

* **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 .index_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 (2023-05-04)

• 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.

3.1.0 (2022-11-08)

* Add Python 3.11 support (no code changes were needed, but now we test this release).
* Add Django 4.1 support (no code changes were needed, but now we test this release).
* Fixed an issue where object caches would not be properly cleared after updating tags, leading
  to stale reads in cases where ``prefetch_related`` is used.
* Change ``TagListSerializerField`` to be a subclass of ``ListField``. This should improve support for API document generation. This change should not affect API behavior, but might affect metaprogramming code, so please procede carefully during this update.
3.0.0 (2022-05-02)

• Backwards incompatible: Tag slugification used to silently strip non-ASCII characters
