Refactor of the clean task added docs/api, which didn't happen
previously. Re-order when things are generated to work around it.
Also, don't show rollup progress on netlify either.
This adds in the legacy docs into the repo and enables automatic deployment via netlify. The netlify-docs.js script will error out the build on netlify on master if we're not on a tagged commit so that it won't redeploy the docs unless there's a new release. If we're not on master or on master with a tagged commit, it will process with the deploy.
Also, this removes the API docs from being published with npm, fixes#4609.
