Commit: https://gitlab.com/garz-fricke/yocto/layers/meta-guf-machine/-/commit/61dd9ca5c61621c98db244d5b89fe09d4405c108

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 immidiatly after the rename.
