Kraken config is incorrect for current 1.1 iteration of the board. #501

Description

@jmeier5261

There are small but subtle changes between versions 1.0 and 1.1 of the BIGTREETECH Kraken 1.1 board. Of note, the Rsense value has changed for stepper drivers on S1-S4. From the BTT Product Wiki:

V1.0:Max 8A driving current for S1-S4(Rsense=22mR)
V1.1:Max 4.7A driving current for S1-S4(Rsense=50mR)

Accordingly, the values for sense_resistor: should change from 0.022 to 0.050 while still maintaining the information to support the older 1.0 revision.

The existing config predates these changes and makes no mention of the need to adjust those values for the current version of the hardware. Opened this issue to track the existing PR #500 given by andrewreid
