Ensure that cards are required in scenarios

[fivegrant]

model_card.json and data_card.json are used in the tests for data and model cards however they weren't listed as resources in resource.yaml

@fivegrant to me those are "ground truth artifacts" and for an integration test we should only need to be able to generate them not necessarily have them mocked. It's another example of live vs offline testing and the different cases. We may want to resource files...
