fix: level in levelshifter too low on high frequencies

The pull-up resistor to 5V was too big causing the levels not raising
high enough to provide a good signal for the WS2812 RGB LEDs. This is
fixed by choosing a smaller resistor and removing the current limiter
from the microcontroller to the source of the levelshifter's MOSFET.
