[TASK] Update screenshots of Sites > Setup --> Edit site settings

[josefglatz]

The screenshots must be updated due the removal of "Site Management > Settings" module which are now available unter "Sites > Setup" → Click on Edit site settings button of one of the existing site if the site has settings.

The renaming of the module labels where already fixed in #374

We plan to update the screenshots after feature freeze as more optical changes are planned currently
