Publish the new buildpack to the Heroku Registry

   still pending, reposting it as an issue to keep track of it.

@steve-chavez yes, sure I can help! However, it is needed to find the original creator who registered the Heroku buildpack for the first time. As per the documentation https://devcenter.heroku.com/articles/buildpack-registry#namespaces-and-buildpack-ownership a buildpack can be owned by an individual (e.g. Heroku personal account) or a Heroku Team. If the latter option has been used you can add me to that Team so I can manage it, otherwise, I would need the user credentials to access.
