Generate enums in Github Actions

[tschaume]

@esoteric-ephemera @tsmathis Regenerating the enums removes the _missing_ classmethod for the VASP calc types. Is that being used/needed anywhere?

I'm not seeing the use of __missing__ anywhere in emmet

I'll also close #1094 in favor of this

sorry, that's _missing_ actually isn't it. But same thing, non-existent as far as I can tell

[esoteric-ephemera]

@tschaume, _missing_ is needed for case insensitivity, see this issue that @munrojm fixed a while ago. Without _missing_, pydantic throws validation errors (checked for that specific MPID in the issue, mp-2048877), adding it back resolves them

_missing_ is a fallback search method for Enum's

I'd like to take a crack at having the action generate a yaml file, and instantiating the enums from yaml. I'll make a separate PR for that
