subscriber: fix docs link to Layer impl for Box

RustDoc didn't actually parse the link to the `Layer` impl for `Box<dyn Layer<S> + Send + Sync>` because the link URL contained unescaped spaces. Therefore, the link reference was treated as normal text rather than as a link reference. This commit replaces the link ref with the escaped version, which works correctly. My bad!
