En héritant de `str` la documentation sera capable de savoir que les valeurs doivent être de type `string` et pourra donc afficher cette `Enum` correctement.

Créez ensuite des attributs de classe avec des valeurs fixes, qui seront les valeurs autorisées pour cette énumération.

                This is not passed as a parameter to the `FastAPI` class to avoid
                giving the false idea that FastAPI would generate a different OpenAPI
                schema. It is only available as an attribute.
