Una aplicación (instance) de `FastAPI` tiene un método `.openapi()` que se espera que devuelva el esquema de OpenAPI.

Como parte de la creación del objeto de la aplicación, se registra una *path operation* para `/openapi.json` (o para lo que sea que configures tu `openapi_url`).

Simplemente devuelve un response JSON con el resultado del método `.openapi()` de la aplicación.
