Any way to get plugins installed and referenced? I can personally have the npm package installed. But not sure how to include it into the config.
`import PasteFromOffice from '@ckeditor/ckeditor5-paste-from-office/src/pastefromoffice';

ClassicEditor
.create( document.querySelector( '#editor' ), {
plugins: [ PasteFromOffice, Bold, ... ]
} )`

Great Branch BTW, dont know why they wont merge it.

Appreciate the PR, however I’ve decided to stop bundling CKEditor in the plugin altogether – defaulting to a CDN build (v5, 27.0.0), and allowing developers to provide a custom build URL. It also offers full control over the editor initialization and configuration.
