docs: remote protocol: bc/bs not mentioned in stop-reply list

Hi,

The remote protocol docs for stop-reply [1] has a list of commands
that accept stop-reply packets as a response:

"The 'C', 'c', 'S', 's', 'vCont', 'vAttach', 'vRun', 'vStopped', and
'?' packets can receive any of the below as a reply."

However, at the definition of 'bc' and 'bs' [2], it's also said:

"Reply: See Stop Reply Packets, for the reply specifications."

Maybe the list from [1] is not meant to be exhaustive, but perhaps
'bc' and 'bs' could be added to it?
