[gnome-builder] devhelp: fix "New documentation page" activation

    devhelp: fix "New documentation page" activation
    
    This wasn't available previously because the action was tied to the layout
    stack (so we can ensure it ends up in the right stack).
    
    This just adds a new action to the "win" action prefix so that we can
    activate it from anywhere in the application.
