tzdata-2024b chaos

Hi!

There's two issues with the latest tzdata-2024b release.

1) "Apr" vs "April" which has confused some broken parsers;
there's a patch for this post-release [0].

2) Both libc++ and libstdc++ appear broken with a separate problem
[1][2][3].

This manifests in Waybar, for example [4].

It's not clear to me if libc++ is broken or not, as people in the bug
may have been testing a clang configured to use libstdc++ (the default),
and I don't have a system to test it on to hand.

Paul Eggert, the tzdata maintainer, notes on the ML in one of the
threads discussing this that rolling back to 2024a is a reasonable
workaround for now, as there's no critical data changes in 2024b [5].
