Retire django-developers and django-users mailing list

[Thibaud Colas]

Following the forum thread (​Proposal: retiring django-users and django-developers mailing lists), we can now move ahead with updating the developer documentation to remove or contextualize references to the django-developers and django-users mailing list.

There is a lot of content that needs removing, but in some cases it might make sense to replace the references to those mailing lists with a link to the Django Forum, or specific forum categories. Also worth noting the django-announce and django-updates mailing list are staying as-is.

Removal tasks

• [ ] remove 2x mailing lists from the ​How to release Django docs
• [ ] Remove django-users from the ​FAQ - How do I do X
• [ ] Remove ​Why hasn't my message appeared on *django-users*? from the FAQ: Getting help
• [ ] Remove ​You might notice we have a second mailing list paragraph from the FAQ: Getting help

Rewrite tasks

• [ ] Rewrite the ​Mailing lists and Forum explanations for django-users and django-developers to explain the mailing lists still exist and contain valuable history
• [ ] Replace the 4x django-users and django-developers mentions on ​Reporting bugs and requesting features to instead point to the forum
• [ ] Replace the django-users and IRC links on the ​What to read next with a link to the ​Django Community page

Do nothing

• Keep the rst_epilog references in the Sphinx config for now
• Keep any references to the mailing lists in historical docs (for example old release notes)
