Update documentation link on Project age

Problem/Motivation

The documentation link on the project page directs to the old book style documentation. That documentation should be migrated to the new system.

A few days ago a doc page for this module was added to the Drupal API guide. I have moved it to the Contributed module guide but it is not linked to from the Project page.

Steps to reproduce

Proposed resolution

A. If the old book style documentation is needed then

1. Create a new guide for Token in the Contributed module guide
2. Migrate the old book style documentation to a page or pages in that new guide
3. Add recently added page → to the guide
4. Update documentation link on the project page to the new guide

B. If the old book style documentation is not needed then update the project page doc link to direct to the
recently added page → to the guide

Remaining tasks

User interface changes

API changes

Data model changes
