Typing Issues with Pydantic and Ruff Linting

[ianhuezo]

Is there a reasonable way to convert to a pydantic BaseModel using httpx? I'm having a bit of trouble since ruff gives a type error of something like:

response = httpx.get(...)
my_json = response.json()
model = MyPydanticModel(**my_json) #throws a typing error that `Any` can't be used

I used to be able to one-line it like in the FastAPI docs here:

MyPydanticModel(**response.json())

Took a look at when that was changed in this PR #923, but it seemed like the user was making a few assumptions before conversion. Namely, he was forgetting that the items may not exist yet where something simple like

_ = data["items"] 

could evaluate to None. Let me know if I'm missing something though.

Seems like a Pydantic question, really.
