boards: sparkfun: Fix incorrect pro_micro gpio-map

The SparkFun Pro Micro header pins are numbered D1, D0, GND, ... from top
left whereas the SparkFun Pro Micro RP2040 and the Adafruit KB2040 boards
are using gpio 0, 1, GND, ... , so the pro_micro: connector gpio-map of
these boards should reflect that.

Please note that the KB2040 uses CircuitPython pin labels D0, D1 which does
not seemt correspond to the Arduino labels D0 and D1 used by the Pro Micro.
