Whitelisting jekyll-webpack

I'm working with gh-pages v228. I want to publish a Jekyll site with some React code bundled with a webpack. Locally I'm using [jekyll/webpack](https://github.com/tevio/jekyll-webpack/) plugin.

Locally it works (e.g. my blog has webpack dependencies - see [repo](https://github.com/VorontsovIE/VorontsovIE.github.io)) and bundles my webpage even in live reloading mode.
But it doesn't work on a hosted version, thus I need to manually bundle my source code and put bundled files under a git supervision.
Nothing critical, but I think it'd be more convenient to bundle code on a github server.

La issue menciona el plugin jekyll/webpack y enlaza a un repositorio de ejemplo. Empieza revisando la allowlist actual de plugins y la gestión de builds alojados de pages-gem; después, compara los requisitos del plugin con las dependencias de GitHub Pages compatibles. Se considera completado cuando el plugin solicitado puede evaluarse para bundling alojado sin requerir bundles confirmados manualmente.
