Explicitly cast help_text used as description to str to resolve lazy translation

Before graphql-core had issues processing descriptions generated from
translatable help_text during schema generation. Involved graphql-core
utilities expect descriptions to be of type `str`, however, the generated
descriptions were of type `django.utils.functional.__proxy__` which caused
concatination with actual strings to fail.
