Use enum value for 'listing_type' in api calls

The bug in the API calls for listing comments and posts within the 'lemmylib' library has been fixed. The 'type_' parameter key was previously incorrectly expecting the entire 'listing_type' enum instance, but it now correctly expects the 'value' attribute of the 'listing_type' enum instance.
