Csse pyd2 510

[loriab]

Description

• Provide a version of QCSchema expressed in Pydantic v2 API lodged in qcelemental.models.v2. It is not accessed by default.
• First three commits are copying in a set of models.v1 into models, applying the models portion of @Lnaden 's Pydantic v2 Overhaul [DNM yet] #321, and copying the result down to models.v2. Only the 4th commit d515a5f is changes to make it all work.
• The outlandish pyproject.toml changes are because to build docs for pyd v2 models one needs a recent sphinx, autodoc-pydantic, numpydoc, etc., but poetry insists it be solvable for py37.
• Ended up pulling in need graphviz #342 to fix and/or see the true errors in docs build.
• It's awkward to deprecate in code, so this is official notice that homegrown AutoDoc will not be in qcdk v2 and could be removed from v1. All of QCArchive uses autodoc-pydantic instead, so this is notice to any downstream models. The autodoc changes from Pydantic v2 Overhaul [DNM yet] #321 will be discarded (sorry, Levi, that was a lot of work iirc.
