ci: Move to new template version v1.1.1
As the new GitLab runners require us to build containers via buildah this change updates us to the latest template version incorporating the change.
To fix CI for the N1SDP, also temporarily restores support for 5.19 in meta-virtualization until 6.1 is supported in meta-arm.
