Review Comment:
At step 3, we will update `lastMaxReadPositionMovedForwardTimestamp` with
following logic chain:
`org.apache.pulsar.broker.transaction.buffer.impl.TopicTransactionBuffer#commitTxn`
->
`org.apache.pulsar.broker.transaction.buffer.impl.TopicTransactionBuffer#removeTxnAndUpdateMaxReadPosition`
->
`org.apache.pulsar.broker.transaction.buffer.impl.TopicTransactionBuffer#updateMaxReadPosition`
instead of `syncMaxReadPositionForNormalPublish`.
