Change show-all keybinding to outline-cycle-buffer in pdf layer 

Emacs 28 adds the outline-cycle-buffer feature. Currently there is no keybinding
to fold the outline of a pdf. So let's replace show-all by it for >= Emacs 28,
because it is easier to remember a single keybinding for folding and unfolding
then having separate bindings for those.
