[Tails-l10n] (pull?)[de] wiki/src/doc/about/requirements.de.…

Hi,

I made a really tiny edit (changed from 1GB RAM to 2GB), should this
translation be also reviewed? Or could it also be pulled directly? I
built the wiki as always and the page is okay.

If not, please review:
https://gitlab.com/spriver/tails.git
branch: de_requirements
commit: d840606c Updated the updated string


Cheers!
