KAFKA-10264; Fix Flaky Test TransactionsTest.testBumpTransactionalEpoch (#9291) 

The test case sends two records before killing broker. The failure is caused when both records are NOT sent in a single batch. The failure of first record can abort second batch and then produces `KafkaException` rather than `TimeoutException`. The patch removes the second record send.
