django 4.0 switched to zoneinfo that might be the cause, does adding this package make the docker build happy?

zoneinfo requires timezone data either installed as a os package in which case isn't installed as a os package currently via the dockerfiles nor is it part of the base image of python:3.8-slim or by installing the tzdata python package. Documentation below.

https://docs.python.org/3/library/zoneinfo.html#data-sources

(https://docs.python.org/3/library/zoneinfo.html#data-sources)Data sources The zoneinfo module does not directly provide time zone data, and instead pulls time zone information from the system time zone database or the first-party PyPI package [tzdata](https://pypi.org/project/tzdata/), if available. Some systems, including notably Windows systems, do not have an IANA database available, and so for projects targeting cross-platform compatibility that require time zone data, it is recommended to declare a dependency on tzdata. If neither system data nor tzdata are available, all calls to [ZoneInfo](https://docs.python.org/3/library/zoneinfo.html#zoneinfo.ZoneInfo) will raise [ZoneInfoNotFoundError](https://docs.python.org/3/library/zoneinfo.html#zoneinfo.ZoneInfoNotFoundError).
