Update Sparkfun Thing Plus RP2040 pins to match board
This fixes some missing and incorrectly-assigned pins for the SparkFun Thing Plus RP2040 protoboard so that they actually match what the board says. This also changes the default SPI pins from the SD card pins to the breakout pins on the side of the board.
