`graphql_schema` introspection doesn't output docstrings descriptions

• What is the current behavior?

Running manage graphql_schema to export the schema.graphql doesn't output the description for types and fields. I've only tested it when the description is described via docstrings, e.g.:

class SomeType(graphene.ObjectType):
    """
    Some description
    """

    field = graphene.String()

but I suspect it also doesn't work when using description= or the Meta class as described here:

• If the current behavior is a bug, please provide the steps to reproduce and if possible a minimal demo of the problem via
  a github repo, https://repl.it or similar.

• Create a schema with at least one type with a description (and/or a field description)
• Run the graphql_schema introspection command to export a schema.graphql file

• What is the expected behavior?

The schema is outputted including field and type descriptions.

• What is the motivation / use case for changing the behavior?

No type or field descriptions are exported.
