Integrate meta-guf-distro/remove-garz-fricke-groupname-from-CI

Commit: https://gitlab.com/garz-fricke/yocto/layers/meta-guf-distro/-/commit/b794c048c44d77f7b788c81bf592c24d87f0ebd9

CI: Reduce 'garz-fricke' references from CI to prepare for group rename

Also did some white space changes like yamlint told me. The multiproject synthax does not allow variables, so that needs to be changed immediatly after the rename.
