Add toggle to pre-publish panel to publish lessons when course is published

[donnapep]

Resolves #7457.

Proposed Changes

Add a Publish lessons toggle to the pre-publish panel. When enabled, any lessons associated with the course are published when the course is published.

Testing Instructions

1. Create a course with some lessons
2. Click the Publish button.
3. On the pre-publish panel, ensure Publish lessons is selected.
4. Click the Publish button.
5. Check that the lessons are published.
6. Create another course with some lessons.
7. Click the Publish button.
8. On the pre-publish panel, deselect the Publish lessons toggle.
9. Check that the lessons are NOT published.
10. Switch the course back to Draft status.
11. Check that the Publish lessons toggle is still deselected.
12. Select Publish lessons.
13. Click the Publish button.
14. Check that the lessons are published.
15. Check that the Sensei icon for opening the Course Settings is still the Sensei green color.

Known Issue

The first time the course is viewed on the frontend, the following notice appears:

@renatho I know you did some work on notices not that long ago, including adding this one. Do you know of a simple way to solve this? If not, then I think I'll leave this as a known issue since the notice goes away on a refresh.
