Quando você cria um gerenciador de contexto ou um gerenciador de contexto assíncrono como acima, o que ele faz é: antes de entrar no bloco `with`, ele executa o código antes do `yield`, e após sair do bloco `with`, ele executa o código depois do `yield`.

No nosso exemplo de código acima, não o usamos diretamente, mas passamos para o FastAPI para que ele o use.
