[Feature]Can't support list type swagger response

like:

class Item(BaseModel):
    name: str
    price: float


@app.route("/", method=["POST"])
@api.validate(json=Item, resp=Response(HTTP_200=List[Item]), tags=["demo"])
def demo():
    item = Item.parse_obj(request.context.json)
    return [item, item, item]

One possible way is to use __root__ pydantic root.

class Item(BaseModel):
    name: str
    price: float


class ItemList(BaseModel):
    __root__: List[Item]


@app.route("/", method=["POST"])
@api.validate(json=Item, resp=Response(HTTP_200=ItemList), tags=["demo"])
def demo():
    item = request.context.json
    return ItemList.parse_obj([item, item, item])

By the way, you don’t need to parse request.context.json again. For the return statement, you can use return ItemList.parse_obj([item, item, item]) or return ItemList(__root__=[item, item, item]).

Has anyone undertaken this issue yet? It’s something I need and I was wondering if I should take a swing at it or if it’s already underway.
