fix(tests): Improve txn summary visual snapshot stability (#27404)

The transaction summary visual snapshots are having some 1-2 second drift and it's causing flakes in the the visual snapshot suite. Since we're using a relative duration <120 seconds (getDuration), it's showing second level resolution and causing visual differences. This will increase the time between transactions to 2 minutes or over, which should hopefully stop the relative times from occasionally breaking visual snapshots.
