Remove the pytz requirement
Django 4.0 made zoneinfo
the default implementation for timezones, rather than pytz
, and a USE_DEPRECATED_PYTZ
setting was added to continue using pytz
if we chose to.
DRF still depended on pytz
for a while and only dropped it in 3.15, when they were forced to in order to support Django 5.0. So we can now remove it too.
