ci: Test using pre-release state of EnergyFlow repo

[j-s-ashley]

To summarize @matthewfeickert in https://github.com/thaler-lab/EnergyFlow/pull/41#issuecomment-2192177572,

• [x] For now, the EnergyFlow installation at line 72 of ci.yml https://github.com/thaler-lab/Wasserstein/blob/ad6d815d2f4483528d4039c954d23bbb286ae220/.github/workflows/ci.yml#L72 can be changed to

  python -m pip uninstall --yes EnergyFlow
  python -m pip install "git+https://github.com/thaler-lab/EnergyFlow.git"

• [ ] The release of fixes for EnergyFlow and full macOS support in Wasserstein will allow the entire Install dependencies step to be removed. https://github.com/thaler-lab/Wasserstein/blob/ad6d815d2f4483528d4039c954d23bbb286ae220/.github/workflows/ci.yml#L69

To give some context on where to go from here, once a new release of EnergyFlow has been made to PyPI then

https://github.com/thaler-lab/Wasserstein/blob/444905b415e84de30d903f949b21e464919ecd3d/.github/workflows/ci.yml#L79-L81

can get replace with just a new lower bound.
