Declare navigation dependency (instead of admin_toolbar) in 4.x

Problem/Motivation

Declare navigation dependency (instead of admin_toolbar) in 4.x.

E.g. the "Add content" block relies on it:

{# Add content buttons #}
        {{ drupal_block('menu_block:content', {
          label: 'Add Content'|t,
          label_display: 'visible',
          provider: 'menu_block',
          follow: false,
          follow_parent: 'child',
          label_link: true,
          label_type: fixed,
          level: 1,
          depth: 1,
          expand_all_items: true,
          parent: 'content:navigation.create',
          suggestion: 'drowl_admin_dashboard_tiles'
        }) }}
