Add support for more foundation models

[Andrew-S-Rosen]

What new feature would you like to see?

We should add the pre-trained SevenNet MLP to the supported MLP methods since it performs so well on https://matbench-discovery.materialsproject.org.

This would entail adding it as a supported calculator method in quacc.recipes.mlp._base.pick_calculator, updating the method type hints in the quacc.recipes.mlp functions to include SevenNet, adding some tests to the test suite, and adding sevenn to pyproject.toml.
