How to support Factory resets

[TobiPeterG]

Currently, Yuga Linux supports Factory resets by creating hidden BTRFS snapshots. see https://github.com/YugaLinux/tik-modules-yuga/blob/main/post/16-prepare-factory-reset . However, this is not optimal as it blocks disk space over time. Instead, it should be investigated, if an OCI image can be used for this instead, introduced in https://github.com/openSUSE/transactional-update/releases/tag/v5.0.0
