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

Beginne mit dem Python-Pfad schema.py, der von tdbpy commit verwendet wird, und verfolge, wie Optional[List[str]] und Optional[Set[str]] vor dem Einfügen konvertiert werden. Reproduziere den gemeldeten DatabaseError mit dem Organization-Beispiel und überprüfe anschließend, dass beide optionalen Collection-Attribute akzeptiert und zum Schema hinzugefügt werden.

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.
