🎩 What? Why?

As described at #8103, the asset configurations do not work for external apps outside of the Decidim main repo.

This is an oversight in the original implementation (#8066) where the webpacker override load path was added through the core gemspec. Obviously, this gemspec is not loaded in the actual applications.

This fixes the issue by applying the override load path directly to the webpacker binstubs during the webpacker install command, as that is the only place where this can be done. In addition, this change broke the assets:precompile task in some occasions which also needs to know the watch paths (additional paths) from the overridden configuration in order to calculate the asset hash to decide whether the assets need to be recompiled or not.
