[Tails-l10n] (review)[de] wiki/src/doc/first_steps/startup_o…

Hi,

I translated
wiki/src/doc/first_steps/startup_options/administration_password.de.po

Please review; I left one string fuzzy because I don't know the exact
translation of "Welcome in Tails" in the German version of the Greeter
anymore.

branch: administration_password_de
991b395: Initial translation, left one string fuzzy


Cheers,
