Mitigate broken test_coalesce_reference_cycle test on dynamo (#94622)
The test has been disabled and shows up on https://github.com/pytorch/test-infra/blob/generated-stats/stats/disabled-tests-condensed.json, but then the JSON file downloaded by the runner doesn't seem to have it.
Disable it explicitly to keep trunk green while investigating.
