Internationalization

[Florian-Schoenherr]

From discord, domain.com/en-US/article with maybe a default of domain.com/article ->en-US

Notes from a noob:
Articles are made up of small sections, which will probably correspond to different fields in a json-object with translations. The default language (in which the maintainers document) will get new additions, which will not be translated immediately. I have 2 suggestions regarding this:

1. if an english translation doesn't have a counterpart in another language, or isn't updated, the article (/section) should show that it is stale
2. for currently untranslated articles, we could use a generated translation and tell the user that it is generated

Might be hard, just my vision of good internationalization+workflow around it.
