www/py-django-graphiql-debug-toolbar instead

*/py-dj42*: Deprecate/Set to expire

* The */py-dj42* ports have no more consumers and are redundant now
  as all the other Django ports have been switched from Django 3.2
  to Django 4.2 in the last few weeks. [1]

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.

net-mgmt/netbox: Create Django 4.2 consumers

* Django 3.2 is currently the "default" version in the ports tree due
  its long term support until April 2024.  Thus ports that are assigned
  to that version will exist until then.

The following ports are required to make the upgrade of
net-mgmt/netbox to the 3.6 release possible because it requires
Django 4.2.

All of the ports listed below were created on the basis of their
respective original ports:

- devel/py-dj42-django-rq
- devel/py-dj42-graphene-django
