KAFKA-15330: Add missing documentation of metrics introduced as part of
KAFKA-15028 (#14480)
I've added details for VerificationFailureRate and VerificationTimeMs.
I considered adding the documentation for the
AddPartitionsToTxnVerification metrics, but I noticed that all the request
metrics simply listed Produce|FetchConsumer|FetchFollower. If we don't already
report the AddPartitionsToTxn request metrics in this file, it doesn't make
sense to add the verification variant. (As well as all the other APIs we report)
Filed a followup jira if we want to redo that whole section.
