Supporting sqlx Json<T>

[ElysaSrc]

I think it'd be nice to support (behind a feature flag) the Json<T> because, currently the typing is lost on this element on the OpenAPI generated file.

@ElysaSrc Could you elaborate bit more how you would like the support to be? How it should behave?

Currently I must annotate all Json fields of my struct that is requested though sqlx with the inner type, I was wondering if maybe it could be inferred so when we have a json it directly infer a T type in the openapi scheme ?

Okay, so it should infer the inner type. This needs some looking into to assess what can be done there.
