Project page links to D7 resources

Problem/Motivation

On the project page, under 'Resources' is this link, http://drupal.org/node/1089574, which directs to Drupal 7 docs.

Steps to reproduce

Proposed resolution

Update page to https://www.drupal.org/docs/extending-drupal/contributed-modules/contrib... →

Major because the old book style documentation is being removed.

Remaining tasks

User interface changes

API changes

Data model changes
