Django 2.2 became End-of-Life on 11th April 2022 and Django 3.2 is the
new LTS (= Long Term Support) release which will be supported until
April 2024.

* Switch the most ports that use www/py-django22 to www/py-django32

* Ports that are not yet ready for Django 3.2 (only three so far) or
  those that have already been set with an expiration date were not
  taken into account.

* Bump PORTREVISION due dependency change where necessary.
