Calling this method also changes the session's totalNumberOfParticipants.

When updating the number of participants for a booking you must pass either participantsChoices or totalParticipants. If you pass participantsChoices for services that have variants, all of the provided choices must exist for the service. Otherwise, the call returns an INVALID_SERVICE_CHOICES error.
