Make start page multilingual
We should have the start page in DE also, now EN only.
This should be the currently used index page
/opt/etherpad-lite/src/templates/indexFAIRKOM.html
However changes do not appear - restart needed?
It seems not to be synced with the git version https://git.fairkom.net/hosting/board.net/-/blob/master/templates/index.html
