weblate: expected outage on 14. 7. 16:00 CEST

Hi, the time has come for another Weblate update (4.6.2 -> 4.7.1). Now we will also update the server from Leap 15.2 to Leap 15.3. We have successfully tested Weblate-4.7.1 on openSUSE Leap 15.3, the update process was smooth. Expecting outage less than 1 hour. Please, let us know if the time of the update does not suit you.
