Make the openQA testing more prominent
Landing pages for GNOME OS are https://os.gnome.org and https://gitlab.gnome.org/GNOME/gnome-build-meta/.
Currently these don't mention the end-to-end testing. Ideas to solve that:
- Just link to it
- Add CI badges for the test-s3-image job or for the tests themselves. There's no easy way to do this - Gitlab provides a badge for the pipeline status as a whole, but nothing for specific jobs.
- StackOverflow suggests creating a badge as part of the pipeline, uploading it as an artifact and then linking to that - which is probably the easiest solution. https://stackoverflow.com/questions/45756371/gitlab-ci-using-badges-for-each-job
- Badge could include Git commit, pipeline ID, other stuff too...
