ci-tooling Linux template should be updated to latest SuSE docker image
@bshah was nice enough to donate a CI build for Juk, but it currently fails.
I think it's because the Linux template https://invent.kde.org/sysadmin/ci-tooling/blob/master/invent/ci-applications-linux.yml refers to a now-deleted Docker image for Suse 5.10.
There is a replacement docker image we've built, https://hub.docker.com/r/kdeorg/ci-suse-qt512, which I suppose is probably the right thing. I don't have time to pop up a MR for it now but wanted to at least note down the issue before I had to go.
Could someone take a look at whether the ci-tooling/invent stuff needs to be updated for newer kdeorg Docker images?
