fixes #2051

Sorry, didn't get my setup ready to generate the snapshots.

@hf-kklein, thank you for your contribution! However, we implement such one-time holidays as “special holidays” (see similar holiday in 2020).

@hf-kklein Check your git repo, I've created a PR that addresses all the issues above as well as adding translations, test cases, and updated snapshots. 🙏

@arkid15r @KJhellico We should probably add a new entry for may_8 victory day in the international holiday group as they're currently in use by France, Czechia, Slovakia, and Ukraine.

I'm not sure if I can come up with a name for it though - USSR-derived ones that are celebrated on May 9th currently use _add_world_war_two_victory_day at the moment
