py-werkzeug: updated to 2.2.2

Version 2.2.2
-------------
-   Fix router to restore the 2.1 ``strict_slashes == False`` behaviour
    whereby leaf-requests match branch rules and vice
    versa. :pr:`2489`
-   Fix router to identify invalid rules rather than hang parsing them,
    and to correctly parse ``/`` within converter arguments. :pr:`2489`
-   Update subpackage imports in :mod:`werkzeug.routing` to use the
    ``import as`` syntax for explicitly re-exporting public attributes.
    :pr:`2493`
-   Parsing of some invalid header characters is more robust. :pr:`2494`
-   When starting the development server, a warning not to use it in a
    production deployment is always shown. :issue:`2480`
-   ``LocalProxy.__wrapped__`` is always set to the wrapped object when
    the proxy is unbound, fixing an issue in doctest that would cause it
    to fail. :issue:`2485`
-   Address one ``ResourceWarning`` related to the socket used by
    ``run_simple``. :issue:`2421`
