Add Power Domain/RTC pins to pinout PDF (similar to S3 variant) #3

Please add a "Power Domain" label to the C3 pinout PDF, similar to the pinout diagram for the S3.

It took me a few minutes to cross reference nomenclature to figure out what I needed via resources like espressif's GPIO summary.

:wave: Looks like @BlitzCityDIY added that to the S3 diagram. She may know how to do it for this.

@tannewt Oh hi!

Quick background: I assumed the C3 would have a lower deep sleep current consumption (Based on the architecture - but that doesn't really make any sense). Upon further inspection it appears that the C3 and S3 have identical consumption of 26.85 μW or 8.14 μA @ 3.3v (based on espressif docs). I was planning to cut off the neopixel from the C3 QT Py if that module indeed had lower consumption, but I'll simply use an S2/S3 instead (which has the neopixel power down option).

Either way, the "power domain" labels would still be a helpful addition. Cheers!
