Highlight incompatibilitiy with Adafruit ecosystem

Browse source 
I try to manage expectation about this board and avoid short circuit or broken sensor.
1) I almost burned myself by mixing LOLIN I2C JST SH accessories and Adafruit QTPy, reverse way, I could have destroyed an Adafruit sensor by connecting it to Lolin S2 Pico.
2) The screen does not work as expected for a build-in screen, DISPLAY is not defined when you `import board`

I did hesitate between making a special section like "Caveats" or highlighting how it deviate from one can expect from a board running CircuitPython.
