This commit fixes a bug in the redesigned about page where if there's no banner image configured for the page, the top of the page where the banner goes is occupied with large white space. Additionally, this commit also fixes a related bug in the admin config area for the /about page where it's not possible to remove the uploaded banner image.
This commit continues on work laid out by 6039b513fe to redesign the /about page. In this commit, we add sections for showing the site admins and moderators.
The lists of admins and moderators display the 10 most recently seen admins/moderators, with a button to display the rest of admins or moderators. Admins or moderators that have not logged in to the site in the last year will not be shown. Clicking on an admin's or moderator's name/avatar will show their user card.
This commit continues on work laid out by 6039b513fe to redesign the /about page. In this commit, we add the site age and a section on the right hand side to show site activities/statistics such as topics, posts, sign-ups, likes etc.
This commit introduces the foundation for a new design for the /about page that we're currently working on. The current version will remain available and still be the default until we finish the new version and are ready to roll out. To opt into the new version right now, add one or more group to the `experimental_redesigned_about_page_groups` site setting and members in those groups will get the new version.
