Make some tests use deterministic torch algorithms

[RaulPPelaez]

This fixes some tests not passing on some architectures due to numerical inaccuraccies (at least on my machine).

@mikemhenry @raimis , try the GPU runner here please.

Tests running here https:/openmm/NNPOps/actions/runs/5660607367

RuntimeError: Deterministic behavior was enabled with either `torch.use_deterministic_algorithms(True)` or `at::Context::setDeterministicAlgorithms(true)`, but this operation is not deterministic because it uses CuBLAS and you have CUDA >= 10.2. To enable deterministic behavior in this case, you must set an environment variable before running your PyTorch application: CUBLAS_WORKSPACE_CONFIG=:4096:8 or CUBLAS_WORKSPACE_CONFIG=:16:8. For more information, go to https://docs.nvidia.com/cuda/cublas/index.html#cublasApi_reproducibility

Looks like I need to add this to the runner

New test here https:/openmm/NNPOps/actions/runs/5661251365

[mikemhenry]

From here https://docs.nvidia.com/cuda/cublas/index.html#results-reproducibility I chose the export CUBLAS_WORKSPACE_CONFIG=:4096:8 since I don't think we are tight on GPU memory

Tests pass!

I setup auto-merge, review required, and status checks. Let me know if that causes any issues @RaulPPelaez @raimis
