Use to_resource_type in PolymorphicAutoSchema

[ADR-007]

Hi!

Pls, change this:

drf-spectacular/drf_spectacular/contrib/serializers.py

Line 19 in b73adbb

'mapping': {c.name: c.ref['$ref'] for c in sub_components},

to:

serializer_model_mapping = {value: key for key, value in serializer.model_serializer_mapping.items()}

        return {
            'oneOf': [c.ref for c in sub_components],
            'discriminator': {
                'propertyName': serializer.resource_type_field_name,
                'mapping': {
                    serializer.to_resource_type(serializer_model_mapping[sub_components[0].object]): c.ref['$ref'] 
                    for c in subcomponents
                },
            }
        }
