[Fr-info] Bzgl. GitLab email confirmation

Moin, hier ein PSA, um Nachfragen vorzubeugen: Die Finf GitLab Instanz wurde soeben updated. Die Email confirmation mails sind so vom Hersteller gewollt und automatisch rausgegangen. ############ Dear GitLab user, As part of our commitment to keeping GitLab secure, we have identified and addressed a vulnerability in GitLab that allowed some users to bypass the email verification process in a recent security release. As a precautionary measure, you will need to re-verify some of your account's email addresses before continuing to use GitLab. Sorry for the inconvenience! ############ Grüße, Sergej
