python: zoneinfo is pretty much broken

https://docs.python.org/3/library/zoneinfo.html

`zoneinfo.available_timezones()[¶](https://docs.python.org/3/library/zoneinfo.html#zoneinfo.available_timezones)` return an empty and any access results something like

```
File "/lib/python312.zip/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 UTC'
```
