Add dialout permissions to documentation

[byarbrough]

After installing the cli on Linux (Raspberry Pi 5) I was getting issues trying to connect to an Arduino Nano 33 BLE Sense Rev2 to flash the firmware. After flashing the firmware via Windows (yuck) I tried to connect over USB to edge-impulse-daemon and got

[SER] Failed to connect to /dev/ttyACM0
Error permission denied, cannot open /dev/ttyACM0
You might need sudo or set the right udev rules

I fixed this by adding my user to the dialout group.

# Must logout or reboot for changes to take effect
usermod -aG dialout $USER

This fixed my ability to flash firmware as well!

If somebody can point me to where the documentation actually lives I'm happy to make the change! (I couldn't find the docs repo)
