docs/fingerprint: update Bloonchipper power numbers
Re-measure power numbers on a Bloonchipper dev board connected to a servo
micro.
Put numbers for the 2 possible idle modes of the MCU by toggling the
slp_s3 line:
- regular idle when the host processor is running
- low power idle when the host processor is suspended
