Retry ONNX tests (the quick way) (#98627)
This is to mitigate a flaky ONNX test in trunk and also improve its reliability till we have https://github.com/pytorch/pytorch/issues/98626 (I figure that this is better than moving the job to unstable).
I try to disable the flaky test https://github.com/pytorch/pytorch/issues/98622, but that won't work as @clee2000 points out because ONNX isn't part of `run_test.py` to download and apply the list of disabled tests.
