Checklist

• Raised initially as discussion Proposal: Drop dependency on pytz in favor of zoneinfo #8562
• This cannot be dealt with as a third party library. (We prefer new functionality to be in the form of third party libraries where possible.)
• I have reduced the issue to the simplest possible case.

Django now uses zoneinfo by default, and backports backports.zoneinfo if the user is not running pyhton 3.9.

pytz support will be dropped in Django 5.0. DRF should switch to using zoneinfo by default to match Django
