Is your feature request related to a problem? Please describe.

As a content creator I want the guide content for the DruxtJS.org website in the CMS.

Describe the solution you'd like

• Setup Drupal backend for Docs / DruxtJS.org
  • Move examples/drupal/drupal-9 to docs/drupal
  • Add Advanced Page content type with Layout Paragraphs content editing experience.
  • Setup menu for content; May experience issue with Tome Sync and Menu Link Content entities, need to confirm.
• Migrate Guide content from Nuxt content files into Drupal.
  • docs/nuxt/content/guide/* -> Advanced page entities in Guide section.
    • Guide / What is Druxt?
    • JSON:API Client
    • ...

Describe alternatives you've considered

Originally https://cms.druxtjs.org was to exist in it's own git-repository, but the benefits of the mono-repo approach is that the content can be used in the documentation, examples sites and automated tests.
