message: docs(docs-infra): in navigation put prerequisites page 'guide/property-binding' before 'guide/attribute-binding'
  Pages 'https://angular.io/guide/attribute-binding' and 'https://angular.io/guide/class-binding' have prerequisite of 'https://angular.io/guide/property-binding' but in navigation the property binding page comes much later.
  The change puts the binding pages in prerequisite order.
