New version of pytz is breaking Django 3.2.x

[Denny Biasiolli]

pytz is not explicitly boud to a specific version, so when installing Django it takes the last one available.
Currently it's taking the 2022.2 version and when launching Django it gives this error:

`
ModuleNotFoundError: No module named 'tzdata'

(...)

backports.zoneinfo._common.ZoneInfoNotFoundError: 'No time zone found with key Asia/Hanoi'
`

Let me know if you need more info/logs

Actually the problem is not in Django itself, I was creating a new repository using only Django 3.2 and the problem does not exists.
In my case, the problem seems to be related to this package: django-timezone-field

This looks like a duplicate of #33814, related to the move to use ZoneInfo.

Your system likely doesn't have the timezone database installed, so pip install tzdata should resolve it for you.
