Mention `node-stdlib-browser` as alternative package in documentation

[niksy]

This package is deprecated but there are a lot of users that still depend on it, or they depend on specific package from this collection.

I’ve created node-stdlib-browser as alternative which is updated and has many other features such as official support for other bundlers.

This PR mentions that package as alternative for anyone looking for updated version.
