[Feature] Translate en-US i18n to de-DE

[Voigtus]

I'm currently working on a translation of the (kinda) new i18n file from eng => ger.

I just remembered I might need to clean up the en-US file, since some of the translations might not be used anymore 😅 But I can remove the unused one from the de-DE file if you create one so no worries! 😄
