Don't ask for password on SUDO for OPi5 images (#21)

The photonvision dev tooling expects the 'pi' user to not ask for password on sudo when running `./gradlew deploy -PArchOverride=linuxarm64`, since this is the default on RPI OS.

We should do the same here so that gradle behaves on Orange Pi 5 devices as well.
