[core] Fix language index mismatches (#3629)

For reasons I am not knowledgeable enough to answer, NACP language and
nn::settings::Language don't match.

PR #3587 however erroneously matched language_index directly to NACP
language which caused those weird mismatches (since idx 2 = French
actually matches up to an NACP language of Japanese). So to get around
that just go back to the mapping of language idx -> nacp language
