devel/py-graphene-django300: Remove expired port

2026-03-31 devel/py-graphene-django300: Obsolete, was used as temporary solution
due compatibility issues. Please use devel/py-graphene-django instead

devel/py-graphene-django300: Deprecate/Set to expire

* The port was used as a temporary solution in 547ee8e902f4 due to
  compatibility issues with net-mgmt/netbox and it's bound to Django 4.2.

  It no longer has any consumers, thus deprecate it accordingly as part
  of the Django 4.2 -> 5.2 migration.

* Although www/py-django42 will not reach its EoL until April, set the
  EXPIRATION_DATE accordingly at the end of 2026Q1 to get a clean cut
  with regard to the quarterly branch.

python: bump all USE_PYTHON=distutils consumers after RUN_DEPENDS removal

Any missed ports, feel free to bump.

Any ports that need setuptools at runtime can have the devel/py-setuptools
manually added back to RUN_DEPENDS, but understand that this practice
is deprecated; see CHANGES for details.

net-mgmt/netbox: Change RUN_DEPENDS

* Switch the port from the repo-copied py-dj42-django* ports to the
  original ones as they're using Django 4.2 now since 680c68fd4d69.

* An exception here is devel/py-dj42-graphene-django, which is renamed
  to devel/py-graphene-django300 because NetBox has known problems with
  newer versions of devel/py-graphene-django.  Add an entry to MOVED for
  it as well.

* Adjust www/py-{dj42-}-graphiql-debug-toolbar accordingly due to the
  rename of devel/py-dj42-graphene-django as described above and to
  avoid installation conflicts.

* Bump PORTREVISION where necessary due changed dependencies.
