Fixes gpio control on the pi 5.
Tested on the pi4 and 5 using kernels 6.6.31 and 6.6.51
If a pi 5 is detected the lgpio is installed. adafruit-blinka is supposed to install the correct library but its doesnt seem to do so. IF adafruit fix this then we can revert this fix.
The code uses gpiozero to detect the pi version as this decodes the pi revision number so can detect all future versions of the pi 5 as well.
