Retry resolving download.pytorch.org with Google DNS (#100509)
We want to retry resolving `download.pytorch.org` one more time with Google DNS as it seems to work on the runner. This is to avoid the intermittent NXDOMAIN error when using AWS local DNS 10.0.0.2, for example https://github.com/pytorch/pytorch/actions/runs/4864714757/jobs/8674570552
