Missing documentation on how to verify T2B1

[maaft]

In docs you can find instructions how to verify self-build firmware for model T and model One.

How can this be done with the new Safe 3?

[matejcik]

the Safe 3 firmware is the same type and format as the TT so the exact same instructions apply.

the only change (which we do need to document) is that the path to the TS3 binary is build/core-r/fimware/firmware.bin, and similarly for the model T the path changes to core-t

[Giszmo]

It's core-R and core-T respectively.
