website-builder image is no longer buildable.

It fails with

ERROR:  Error installing jekyll:
	The last version of sass-embedded (~> 1.54) to support your Ruby & RubyGems was 1.57.1. Try installing it with `gem install sass-embedded -v 1.57.1` and then running the current command again
	sass-embedded requires RubyGems version >= 3.3.22. The current RubyGems version is 3.1.6. Try 'gem update --system' to update RubyGems itself.

When RubyGems is updated the jekyll cannot be installed as sass-embedded is not provided for Alpine (musl-based) Linux.

sassc support was removed in https://github.com/jekyll/jekyll-sass-converter/pull/140

We have few ways forward

• Freeze jekyll version at the last suported
• Switch to non-Alpine ruby base image - it is based on Ubuntu and the empty size is almost 900 MB
• Switch to Fedora based image - it will be probably smaller but swiches from Ruby 2 to Ruby 3

In the latter two cases the Dockerfile wil require significant upgrade due to node.js installation and dependencies not provided by the new distro.
