Chore: Renames has_live_preview column to previewable. (#4039)

## Because
The new column name is Railsyer.


## This PR
- Adds a migration to rename lesson.has_live_preview to
lesson.previewable
- Changes all instances of has_live_preview to be previewable in the
codebase.


## Issue
Closes #4003 

## Additional Information
As a matter of clarification, the task assumed the has_live_preview
column was in the project_submissions table. It was actually on the
lessons table.
