Update the Webpack Encore configuration

As commented by `@Seb33300` in #6590 (comment) we should have checked the latest recipe for Webpack Encore (https://github.com/symfony/recipes/blob/main/symfony/webpack-encore-bundle/2.0/package.json) when upgrading its configuration.

So, I just did that and added the missing packages.
