Bundle Babel Plugin in Monolite

[kube]

Bundle it with Monolite will prevent installing another dependency, and simply do:

// babel.config.js
module.exports = api => {
  return {
    presets: [
      // ..
    ],
    plugins: [
      'monolite/babel',
    ]
  }
}

This will also permit to synchronize the plugin and the library development.
