Publish one or more course sections (and their lessons). Provide either target_ids (an array of course-section public IDs) or target_all: true to publish every section of the course. Returns 422 if neither is supplied.
The action runs asynchronously — poll with GET /api/v2/courses/sections/publish_actions/{id} and compare performed_count to target_count to track progress.
Set auto_enroll: true to grant existing course enrollees access to the newly published sections. Pair with send_email: true to notify them.
Use scheduled_for (ISO 8601, must be a future datetime) to defer the publish.
