What problem does this PR solve?

Issue Number: close #26997

What is changed and how it works?

TestWriteReorgForColumnTypeChangeOnAmendTxn begins an explicit pessimistic transaction and locks some keys. But it does not close the session at the end of the test. So the ttlManager keeps updating TTL for the transaction, leading to a goroutine leak.

This PR closes the session at the end of the test.

Check List
