xstatic-jquery.quicksearch has never been released using the OpenStack
release prociess with openstack/releases repository.
To sync the release history in openstack/releases and PyPI, we need to
release a new version, so the xstatic version is bumped.
README is also updated to satisfy what PyPI expects.
This is required to pass the validation in openstack/releases repo.
