The list of languages doesn't need to be translated, so there is no reason to keep it in the language files. Moved to its own
file (/_data/languages.yml). Now the language dropdown parses the languages from there.
This change is also needed for the migration to Weblate (which would ask translators to translate the language names).

It's not compatible with Weblate and will be not needed after the migration
