[ci]: blocklist test_autograd for core #45

🐛 Describe the bug

On v100, ninja will crash when running ninja:

home/jenkins/pip/bin/python3
/home/jenkins/pip/bin/ninja
Python 3.13.5
/home/jenkins/scripts/shard_with_label.sh: line 128:  1643 Segmentation fault      ninja --version

see https://community-ci.openruyi.cn/ruyici/job/PytorchCi/job/10-k1-shard-ci/2941/console

this will lead the case failed:

"test_autograd.py::TestAutograd::test_multi_grad_all_hooks"

see log

Unblock the process to upstream, so add it temporarily.

And it is okay to run with the same CI job. Cannot reproduce it on v100 manually also.
