Background
To gather feedback on new book styling, we would like to deploy the new book renderer to all projects along with the OCG renderer (similar to single-article PDFs)
Acceptance criteria
- Add $wgCollectionFormats['electron'] = 'PDF'; Make sure it comes before other similar formats because we want this option to be displayed first in the drop-down list.
- Deploy new renderer to all projects
- Allow user to choose between old and new book renderer
