Since we're running jmh-based-test only on the latest LTS, when LTS changed from 21->25 it also changed the memory allocation profile such that we need to tune the assertion parameters in InstrumentGarbageCollectionBenchmarkTest. This here says double_sum memory allocation must reduce by 97+-4%, when going from immutable_data to reuseable_data mode. Previously it was 97+-2%.
