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

Tái hiện lỗi ZoneInfo("US/Central") được nêu trong một image python:slim, sau đó kiểm tra cách image slim cài đặt các gói Debian sau khi chuyển sang Trixie. Xác minh liệu tzdata-legacy có khôi phục các khóa múi giờ legacy hay không và xác định những biến thể python:slim nào cần được bao phủ; hoàn tất khi lookup bị ảnh hưởng hoạt động mà không làm hỏng các bản build image.

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")

Traceback (most recent call last):

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.
