chore 📦: Update setupacdc.yml to include Ubuntu release upgrade and kernel reboot steps

Added new steps to the setupacdc.yml file to ensure a more robust Ubuntu installation process, including running the `do-release-upgrade` command and rebooting if a kernel update occurs. This change aims to improve the overall stability of the Samba AD DC role deployment.
