Exclude two of the tests that fail in github actions...

test/hotspot/jtreg/ProblemList.txt line 93:

Since `TestAllocHumongousFragment` and `TestClassLoaderLeak` still fail in [some configs](https://github.com/earthling-amzn/shenandoah/actions/runs/4874732691), I'd leave them in the problem list until they are fixed, perhaps by reproducing on those platforms. At least one of the flagged failure modes for TestClassLoaderLeak (the failing assert) is likely fixed in Kelvin's upcoming PR, so we can revisit these again following that PR as well.
