Updated german language file

Hello Teddy!

I have completed the German translation of the theme (though not perfect) and released it for review.

https://translate.www.ads-software.com/projects/wp-themes/marianne/de/default/

The team at @polyglots told me that I need Project Translation Editor rights.

You could initiate this with a PTE request at make.w.org/polyglots.

Can you help me further?

Greetings
Michael
