doc: better linkaged to node-addon-api
One of the comments we got at the N-API workshop at NodeConfEU was that we should have a better link to node-addon-api and the docs in the main API docs for N-API. The goal being to help people find node-addon-api and potentially start with the node-addon-api docs instead if they are using C++.
This expands and strengthens the link along with a recommendation that starting with the node-addon-api docs might make sense.
