Use <书社:apply-attributes-to-root> to add version

Use <书社:apply-attributes-to-root> to add version

Now that application happens after every stage, it is simple enough to
just inject an `<书社:apply-attributes-to-root>` into the result
fragment prior to application, rather than supporting an entirely
separate `and-version` param (which may not have been properly applied
in recent commits).
