docs: Validate the body of a response from a flask view.
  
      Like `validate_body`, this function compares a json document to a
      jsonschema specification. However, this function applies the schema to the
      view response.
  
      Instead of the view returning a flask response object, it should instead
      return a Python list or dictionary. For example::
  
          from snapstore_schemas import validate_output
  
          @validate_output({
              'type': 'object',
              'properties': {
                  'ok': {'type': 'boolean'},
              },
              'required': ['ok'],
              'additionalProperties': False
          }
          def my_flask_view():
              # view code here
              return {'ok': True}
  
      Every view response will be evaluated against the schema. Any that do not
      comply with the schema will cause DataValidationError to be raised.
