[meta-request] [docs] Generate docs for the Meteor API docs website

(meta-enhancement request for at least "react-meteor-data")

Given that these packages are actively maintained, core-published, and mentioned in the [Meteor Guide for React](https://guide.meteor.com/react.html#data), I would expect that the documentation for "react-meteor-data" also be on Meteor's API docs under the "Packages" sidebar subheading. I think it would make the docs more digestable and discoverable for any user, especially newcomers.
