[recipes] Add more content warning icons in the detail page

[Matthias Clasen <matthiasc src gnome org>]

commit 46f50dc0fd70f5e5f3215f700f479c88b9a13d55

    Add more content warning icons in the detail page
    
    We show icons for gluten and dairy now. I haven't used the egg
    warning icon yet, since we don't have a dietary restriction flag
    for it yet.
