* Fix: Add $SUDO prefix to transactional-update commands in install script

This commit addresses an issue in the k3s install script where the transactional-update commands did not include the $SUDO variable. This omission caused the script to fail if sudo was not used. Adding the $SUDO prefix ensures that the script runs correctly in all environments.
