Input and output schemas are now visible on a model's API page

A model's API page now renders its input and output schema as a proper reference: field names, types, defaults, minimums and maximums, whether a field is required, and so on, laid out the same way for every model.

This is the same schemas.prediction.input and schemas.prediction.output data available from the model version endpoint, now visible without making a request yourself.
