NPM @babylonjs/core package is missing from the registry

https://doc.babylonjs.com/resources/babylonjs_and_reactjs

The docs refer to install babylonjs via @babylonjs/… npm libraries, all of which appear to be broken or missing right now. Either the docs need to be updated, or the libraries in the NPM registry need to recovered somehow…?

Works flawlessly for me:
