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

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):
  File "/usr/local/lib/python3.10/zoneinfo/_common.py", line 12, in load_tzdata
    return importlib.resources.open_binary(package_name, resource_name)
  File "/usr/local/lib/python3.10/importlib/resources.py", line 43, in open_binary
    package = _common.get_package(package)
  File "/usr/local/lib/python3.10/importlib/_common.py", line 66, in get_package
    resolved = resolve(package)
  File "/usr/local/lib/python3.10/importlib/_common.py", line 57, in resolve
    return cand if isinstance(cand, types.ModuleType) else importlib.import_module(cand)

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.

在 python:slim 镜像中重现所示的 ZoneInfo("US/Central") 失败，然后检查 slim 镜像在迁移到 Trixie 后如何安装 Debian 软件包。验证 tzdata-legacy 是否会恢复旧版时区键，并确定哪些 python:slim 变体需要覆盖；当受影响的查找能够正常工作且不破坏镜像构建时，即视为完成。
