docs: Fixes two issues with the sencha created JSB:
  
              - All extjs urls are prefixed by ``../static`` instead of
                ``/static`` (no idea why).
              - We assume static files are served at ``/static``, but collectstatic may
                not build files in ``static/``. Therefore, we replace ``/static`` with
                the relative path to ``settings.STATIC_ROOT``.
