Python schema doesn't accept optional attributes of types ```List``` and ```Set```

Describe the bug
The Python schema.py does not allow attributes to be the type of List or Set, when they are meant to be optional.

To Reproduce
When I try to commit the following code using tdbpy commit:

class Organization(DocumentTemplate):
    name: Optional[str]
    id: Optional[str]
    identifier: Optional[Identifier]
    additionalIdentifiers: Optional[Identifier]
    address: Optional[Address]
    contactPoint: Optional[ContactPoint]
    roles: Optional[List[str]]

I get the following error message:

            "vio:type": "text"
        }
    ]
}

Same happens when roles: Optional[List[str]] is changed to roles: Optional[Set[str]].

Expected behavior
I would expect the changes to be accepted and added to the schema.

System information (please complete the following information):

• OS: Docker
• terminus-client-python 10.2.3

Inizia dal percorso Python schema.py utilizzato da tdbpy commit e traccia come Optional[List[str]] e Optional[Set[str]] vengono convertiti prima dell’inserimento. Riproduci il DatabaseError segnalato con l’esempio Organization, quindi verifica che entrambi gli attributi di raccolta opzionali siano accettati e aggiunti allo schema.
