fix: update warning message for missing sudo access

The warning message for users without sudo access has been updated to provide clearer instructions. Instead of just suggesting manual installation, it now also suggests running the script as root using `./${selfname} install`. This change improves user experience and helps them resolve dependency installation issues more effectively.
