We've introduced new issues workers in a previous MR
https://gitlab.com/gitlab-org/gitlab/-/merge_requests/72802
that now comply to NamespacedClass cop offences tracked in
issue https://gitlab.com/gitlab-org/gitlab/-/issues/321982.

Now that we have the new workers in production, we can change
enqueueing jobs with new workers.

We still keep the old workers around in case some of the jobs
are still in old queues and need to be processed by the old
workers. We'll be removing the old workers in a future release.

Push in some quick and dirty changes. This work is not complete nor
is it fully correct, but I do not want to hold up this work for two
weeks. I will ask the creator to make a follow-up issue for 14.7 for
me to give this page the fuller once-over it truly needs.
