119298: backupccl: bump expected pushes in TestCleanupIntentsDuringBackupPerformanceRegression r=dt a=stevendanna

This test runs a workload that _expects_ 1000 txn pushes. We then assert that we don't see more than 1100, leaving some room for other transactions.  Occasionally this test fails because we see a few hundred more than that.

Since this test is present to catch large regressions in intent resolution, I think bumping this number is not too unreasonable since new background processes have been added to the database since the time it was added.

Epic: none
Release note: None
