Improve project documentation

Changed

Context

The add child page link doesn't include parameters to populate the form with project/documentation references.

View on GitLab #3595876 Configure multiple content types as allowed children per enabled content type Status: Active

Questions

Can I have project features under a book page?
Yes, but the add child/sibling links don't work, set manually in the outline.

How about standardizing the structure?
IE: features/FEATURE-DOCS.

How about a view that lists features w/ summary as an outline?
Example: https://contrib.drupalarchitect.info/project/inventory/documentation/236-maintenancechore-tracking

Use documentation content type, or feature task type?
The idea with the task type is that a task could become a feature and be the place for documentation.

TODO

Add a Feature content type
