CI: add extra VMs for certain tests (#5713)

* Remove superfluous VM.

* Add extra VM group.

* More platforms, add scripts.

* [REVERT THIS] Shrink matrix to only the tests we are interested in.

* Fix some tests.

* Skip snap tests on Ubuntu VMs for now.

* Skip xfs_quota tests on Alpine VMs due to ansible.posix.mount failing.

* Revert "[REVERT THIS] Shrink matrix to only the tests we are interested in."

This reverts commit 2e98e163db.

* Stick to Alpine and Ubuntu 22.04 for now.
