Fix test workflow GitHub Action

[jacobbieker]

Describe the bug

The test GitHub Action workflow is failing on installing PyTorch or PyTorch Geometric.

To Reproduce

Steps to reproduce the behavior:
Look at the Actions tab of the repo, and the failed test runs.

Expected behavior

PyTorch and PyTorch Geometric should be installed successfully so that the tests can run.

Additional context

We also want to keep up with the latest PyTorch Geometic/PyTorch/Python versions.

Hi, so there's currently no support for 2.0.0/2.1.0 for torch on Python 3.12 and this appears to be the test that's failing. Is it alright to skip these combinations on the workflow.yaml until Torch releases it? pytorch/pytorch#110436 (also nothing here too: https://download.pytorch.org/whl/torch/)
