Expose assignment.is_gradable in the dashboard API

This is a potential fix for:

• https://github.com/hypothesis/product-backlog/issues/1608

This will allow the FE to base the decision to show the "sync grades" button both on the feature flag (part of the JSConfig dictionary) and the current assignment's is_gradable value.

@acelaya Can you double check if this approach makes sense? I reckon we need both the FF in JSConfig and this new value. If the FF is enabled we'd still shouldn't show the button to sync grades for non-gradable assignments.

Testing

• Check the new values is present on the JSON response and that that doesn't cause any issues

Yep, I think it makes sense. It's the only way to allow displaying auto-grading-related info without displaying the button to sync grades.

Great, then I think we can merge this independently and tackle the FE side when there's some capacity for it.
