MAX31865 PT100 Guide rtd_reference_r: 400 instead of 430 #110

It seems that while rtd_reference_r: 430 might have been correct for SKR boards, the correct value seems to be closer to 400 for the Spyder and Octopus boards people are using today.

I set up my Voron 2.4 with a PT100 stick with a Spyder board and ended up troubleshooting extruder clicking with the documented settings. Only when I decided the issue was lower than reported extruder temp did I find out the rtd_reference_r config should be 400 instead of 430.
