[devhelp] Use webkit_navigation_policy_decision_get_navigation_action()

[Frederic Peters <fpeters src gnome org>]

commit 05659428acc6da4e6a85d37d9e0d3b00e6adde9d
Author: Sébastien Wilmet <swilmet gnome org>

    Use webkit_navigation_policy_decision_get_navigation_action()
    
    Because
    webkit_navigation_policy_decision_get_navigation_type(),
    webkit_navigation_policy_decision_get_request(), etc
    are deprecated.
    
    The replacement is trivial, but requires WebKit2GTK+ version >= 2.6.
    Anyway "webkit2gtk-3.0" was not correct, it should have been
    "webkitgtk-3.0", so I guess everyone was already using webkit2gtk-4.0.
