[recipes] Return translated strings from recipe getters

[Matthias Clasen <matthiasc src gnome org>]

commit 684ed9d18a3b1925e8c0712b014ab42d55d12d6d

    Return translated strings from recipe getters
    
    Note that this makes gr_recipe_get_description do something else
    than g_object_get (..., "description", ...). Just something to
    be aware of.
    
    We are doing the same for name, description, instructions, cook
    time and preparation time.
