cuGraph: CUDA 12 testing

[jakirkham]

Currently CUDA 12 testing on some cuGraph packages is skipped

https://github.com/rapidsai/cugraph/blob/0a2a2454c349f5375938ddd2fddff0e9c417b52e/ci/test_wheel_cugraph-pyg.sh#L48

https://github.com/rapidsai/cugraph/blob/cc4199d86da520b6e6d92bd97e0110fb1c83b2a8/.github/workflows/test.yaml#L79

Would be interested in understanding why that is the case and figuring out how we can enable testing here

We can add CUDA 12 testing, just have to manually specify the index URL. Hopefully we will move towards an environment where that isn't required after we finish the edge_index changes which should remove the need for those additional packages in CI.

Thanks Alex! 🙏

Where is the edge_index work being tracked?

These tests are only skipped on arm64 now due to pytorch issues.
