Choice field is not serialized as string

NetBox version

Python version

3.10

Steps to Reproduce

Create Aggregate. Go to API and List Aggregates

Expected Behavior

The family field is a string as specified in openapi spec. Or openapi-spec is changed to specify this field as an object in the response.

Observed Behavior

The family field actually is an object:

      "family": {
        "value": 4,
        "label": "IPv4"
      },

This violates the definition.

Removing @extend_schema_field(OpenApiTypes.STR) from class ChoiceField produces in this case a more correct API definition:

                    "family": {
                        "type": "object",
                        "properties": {
                            "value": {
                                "type": "string"
                            },
                            "label": {
                                "type": "string"
                            }
                        },
                        "readOnly": true
                    },

instead of

                    "family": {
                        "type": "string",
                        "readOnly": true
                    },
