publish_content_views.py fails in Satellite 6.8

[tempacct791]

The error is with the helpers.post_json() call. Running it returns an error message:
{ 'displayMessage': 'Could not find environments for promotion', 'errors': ['Could not find environments for promotion'] }

Through a web search, and then verified on a real execution, replace line:
"environment_id": target_env_id,
with
"environment_ids": [target_env_id],
