ci: Handle reboot for transactional update systems

+### podman_transactional_update_reboot_ok
+
+This variable is applicable only for transactional update systems.
+If a transactional update requires a reboot, the role will proceed with the
+reboot if `podman_transactional_update_reboot_ok` is set to `true`. If set
+to `false`, the role will notify the user that a reboot is required, allowing
+for custom handling of the reboot requirement. If this variable is not set,
+the role will fail to ensure the reboot requirement is not overlooked.
+For non-transactional update systems, this variable is ignored.
