Add group gpio to homeassistant user

Hopefully the right place to post this

Running dietpi v6.13

I was struggling to access raspberrypi gpio using Dietpi optimized Homeassistant. Noticed that the manual install added the user to the gpio group. Added homeassistant to gpio group and gpio ‘things’ popped right up in HASS and started working!

before: homeassistant : nogroup dialout dietpi
usermod -a -G gpio homeassistant
after: homeassistant : nogroup dialout gpio dietpi

Also/fyi - I do not have RPi-GPIO installed
