Change project url/slug to match new name

The project was renamed from 'Docker - Standalone' to CiviCRM container building. Please change the url/slug for the project in the Settings > Advanced area in gitlab so that it matches the new name, eg /civicrm-container-building/ instead of /docker-standalone/. Fix any breakages that result from this rename.
