3.0 documentation for TwigExtensions still references Twig extensions from 2.6

[Dodger77]

In the Twig extensions documentation (https://docs.sulu.io/en/3.0/reference/twig-extensions/index.html) there are still the Twig extensions:

• sulu_content_load
• sulu_content_load_parent
• sulu_meta_alternate
• sulu_meta_seo
• sulu_seo

, but some new are missing, e.g.:

• sulu_article_load
• sulu_page_load

Some still reference the old name:

• sulu_navigation_root_flat → sulu_page_navigation_root_flat
• sulu_navigation_root_tree → sulu_page_navigation_root_tree
• sulu_navigation_flat → sulu_page_navigation_flat
• sulu_navigation_tree → sulu_page_navigation_tree
• sulu_breadcrumb → sulu_page_breadcrumb
• sulu_navigation_is_active → sulu_page_navigation_is_active
