Drupal 11 site creation from the Pantheon dashboard now available

Drupal 11 is now available as an option when creating a new Drupal site on Pantheon. Previously, in order to create a new Drupal 11 site you had to first create a Drupal 10 site and then manually upgrade to Drupal 11 via Composer.

See related documentation for how to create new CMS sites on Pantheon.
