 * Dashboard Layout: starter content shipped with the experiment.

 * so the dashboard renders something meaningful the first time a user opens
 * it. Plugins and themes can layer their own callback on top of the same
 * filter to extend or replace this set.

 * Appends the bundled `core/hello-world` instance to the default layout
 * unless something earlier in the filter chain already added it.
 *
 * Only contributes to the bundled `gutenberg_dashboard` surface; other
 * dashboards are left untouched.
 *
 * @param array  $dashboard_layout Default layout produced by previous
 *                                 callbacks on `gutenberg_dashboard_default_layout`.
 * @param string $dashboard_name   Identifier of the dashboard surface
 *                                 receiving the default.
 * @return array The layout extended with the bundled widget instance.
