Update .po files after pushing new string

I was too slow, so this also includes the Russian, Bulgarian and German
translation for this string plus a couple more Danish updates.

Pick the old translations for the updated string

Since this was just a fix for a typo, Transifex allowed me to simply pick
the existing translations for the previous string.

Also fixed a newline vs '\\n' bug in the Dutch translation.
