Ruby Sass has reached end-of-life and should no longer be used

Hi! I've gem install riemann-dash and got this:

Fetching sass-3.7.4.gem

Ruby Sass has reached end-of-life and should no longer be used.

* If you use Sass as a command-line tool, we recommend using Dart Sass, the new
  primary implementation: https://sass-lang.com/install

* If you use Sass as a plug-in for a Ruby web framework, we recommend using the
  sassc gem: https://github.com/sass/sassc-ruby#readme

* For more details, please refer to the Sass blog:
  https://sass-lang.com/blog/posts/7828841

Please consider. Thanks for great tool! .
