Include tzdata-legacy in python slim images after move to Debian Trixie?

Reproduza a falha mostrada de ZoneInfo("US/Central") em uma imagem python:slim e, em seguida, inspecione como a imagem slim instala pacotes Debian após a mudança para Trixie. Verifique se tzdata-legacy restaura as chaves legadas de fuso horário e determine quais variantes de python:slim precisariam de cobertura; considera-se concluído quando o lookup afetado funciona sem quebrar os builds da imagem.

This may be an expected breaking change, but running the following python code in python:slim stopped working yesterday with the move to Debian Trixie :

>> from zoneinfo import ZoneInfo
>> ZoneInfo("US/Central")

ModuleNotFoundError: No module named 'tzdata'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/usr/local/lib/python3.10/zoneinfo/_common.py", line 24, in load_tzdata
    raise ZoneInfoNotFoundError(f"No time zone found with key {key}")
zoneinfo._common.ZoneInfoNotFoundError: 'No time zone found with key US/Central'

This could break existing users that are depending on those timezone strings being available like they were before. This is apparently an expected change in Trixie that installing the tzdata-legacy package would resolve, so throwing that out as a possible mitigation.
