027+dev: bundle exec rails assets:precompile don't work

[froger]

As newest version of decidim don't use the sass gem but the new dart alternative, the gems won't compile. There are two options to consider:

1. Add a webpack configuration to use sass gem while on alpine
2. Add the necessary executables to run dart-node.

Reference:

• sass-embeded, decidim sass loader

  The sass-embedded runs the Dart Sass embedded compiler as a separate executable

Known fix:

1. create a new decidim sass loader, using the sass gem, and add the overrides. (/config/webpacker/custom.js)
2. add the gem sass to the gemfile

As this issue states, we will need to wait before supporting sass-embedded in decidim-sass-loader. So I will go for adding the known fix while alpine is not supported.

We switch on debian, this is not anymore an issue.
