update language_de.h (#6986)

There was quite a lot to translate this time. I'm not absolutely confident with the whole UBL stuff and it's a PITA to translate. I don't use any kind of levelling myself as i just have a perfectly level cast aluminium plate as bed.
So maybe someone who really uses it might take a closer look at it after it's merged.
