python: usage with apis expecting pydantic types

[joprice]

Is there any pattern for generating a type that is annotated in a way that is usable by pydantic. Some libraries rely on it for generating a schema by calling model_json_schema on the type. Pydantic defines its own dataclasses, but the docs say that it has some compatibility with stdlib dataclasses:

I've tried a few combinations to generate a class that it likes, but haven't yet been able to get it to recognize its properties.

Related discussion here, since being able to add arbitrary annotations might solve one piece of this fable-compiler/Fable.Python#48

Since it would be difficult to get things like discriminated unions and string enums working with pedantic, I'm going a different route for now of generating the json schema using a myriad plugin.
