No Pydantic v1, o método era chamado `.dict()`, ele foi descontinuado (mas ainda suportado) no Pydantic v2 e renomeado para `.model_dump()`.

Vamos criar uma **dependência** do FastAPI com `yield` que fornecerá uma nova `Session` para cada requisição. Isso é o que garante que usamos uma única sessão por requisição. 🤓

Então, criamos uma dependência `Annotated` chamada `SessionDep` para simplificar o restante do código que usará essa dependência.
