Translations for "pos_*" not found

[arildm]

Translations for attribute values have moved around a bit. In msd.html, there are references to translation keys like 'pos_JJ'. The translation was moved in spraakbanken/korp-frontend-sb@b3961a3 into attrs.pos.translations, which was later removed in spraakbanken/korp-frontend-sb@f66525f (2022-03-23), probably as settings were moved to backend. They are now present in the /corpus_config response from the backend, under attributes.pos_attributes.pos.translation.

So we need to load that properly into the localization mechanism, I guess.
