[german.nsi] Little fixes

Line 6: "auf dem" instead of "am" (oriented at https://support.microsoft.com/de-de/kb/140443; more commonly used)
Line 41: "aus" instead of "in" (makes more sense imo)

Anyone else fluent in German can discuss for sure. Only because I changed something it does not mean it is *completely* right, eh? ;-)
