enable espaloma tests on python 3.12

Need to update espaloma to use newer dgl, I think I have done this but need to follow up

espaloma 0.3.2 would require
      │     └─ dgl 1.1.2.*  with the potential options
      │        ├─ dgl 1.1.2 would require
      │        │  └─ python_abi 3.10.* *_cp310, which can be installed;
      │        ├─ dgl 1.1.2 would require
      │        │  └─ python_abi 3.11.* *_cp311, which can be installed;
      │        └─ dgl 1.1.2 would require
      │           └─ python_abi 3.9.* *_cp39, which can be installed;

This would also enable osx-arm64 support since we have builds for that arch on newer dgl
