Draft: Resolve "[German] FAIRes digitales System instead of FAIR digitales System"

Closes #42 (closed)

I am just opening this MR here as a reminder. I will only add a commit here when there are no other merge requests in order to avoid merge conflicts.

Since for our term FAIR digital object we have a German exact synonym "FAIRes digitales Objekt", I am assuming that we won't have a lot of discussion about adding the equivalent German synonym to our term FAIR digital system?
