readOnly property not marked as optional in the generated model

Inizia eseguendo la riproduzione OpenAPI 3.1 fornita con openapi-python-client 0.22 e ispezionando il modello Bug generato e l’utilizzo di POST. Traccia il punto in cui vengono convertiti i campi readOnly e required; il lavoro è completato quando i campi readOnly non sono obbligatori per l’input POST, pur rimanendo disponibili nei modelli di risposta generati, con copertura di regressione.

Describe the bug
Fields marked as readOnly in a schema in the OpenAPI document are not set as optional in the generated model.
This makes them required in the body of any POST request in which this model is used, defeating the purpose of using the readOnly property.
