Cannot build with version 1.4.8 of cheatset

The problem is that cheatset relies on: sanitize

• https://rubygems.org/gems/cheatset/versions/1.4.8

sanitize latest version below version 6 is version 5.2.3

• https://rubygems.org/gems/sanitize/versions/5.2.3

This version relies on: nokogumbo version 2.

nokogumbo is no longer maintained as a separate distribution (from this point on it is included in nokogiri), but the older versions do not work with Ruby version 3.

Please see: https://github.com/rubys/nokogumbo/blob/master/ext/nokogumbo/nokogumbo.c#L492C10-L492C26

rb_cData is no longer supported in Ruby since version 3.

6.186 An error occurred while installing nokogumbo (2.0.5), and Bundler cannot
6.186 continue.
6.186
6.186 In Gemfile:
6.186   cheatset was resolved to 1.4.8, which depends on
6.186     sanitize was resolved to 5.2.3, which depends on
6.186       nokogumbo

So I am pondering relying on a Ruby version 2 base image.

The more recent releases are on Ruby 3, based on cheatset 1.4.6.
