The type to use for the response.
It could be any valid Pydantic *field* type. So, it doesn't have to
be a Pydantic model, it could be other things, like a `list`, `dict`,
etc.
It will be used for:
* Documentation: the generated OpenAPI (and the UI at `/docs`) will
show it as the response (JSON Schema).
* Serialization: you could return an arbitrary object and the
`response_model` would be used to serialize that object into the
corresponding JSON.
* Filtering: the JSON sent to the client will only contain the data
(fields) defined in the `response_model`. If you returned an object
that contains an attribute `password` but the `response_model` does
not include that field, the JSON sent to the client would not have
that `password`.
* Validation: whatever you return will be serialized with the
`response_model`, converting any data as necessary to generate the
corresponding JSON. But if the data in the object returned is not
valid, that would mean a violation of the contract with the client,
so it's an error from the API developer. So, FastAPI will raise an
error and return a 500 error code (Internal Server Error).
