[Bug 1995864] Re: UnknownTimeZoneError: 'Europe/Kyiv' in python3-tz

[Robie Basak]

Looks like this was "fixed" upstream by updating the embedded database
by pulling in IANA 2022b at
https://git.launchpad.net/pytz/commit/?id=fbe098e6d2f78765821c2688fd00db8dab40bbef

So I'm guessing this is failing for users who now have Europe/Kyiv set,
and pytz/python-tz/python3-tz cannot find it?

The update in tzdata was to link the old name Europe/Kiev, so I think
that should be a workaround for now?

We can certainly try to cherry-pick the Kiev->Kyiv rename. But
separately I wonder if this needs fixing "properly" by avoiding the use
of embedded code like this, or if that wouldn't be practical for some
reason.
