Sass-rails dependency soon to be deprecated

[wvengen]

When updating gems, I get a warning:

Ruby Sass is deprecated and will be unmaintained as of 26 March 2019.

• 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: http://sass.logdown.com/posts/7081811

See also https://github.com/rails/sass-rails/issues/420.

Brightcontent depends on sass-rails, which will be deprecated very soon. Let's move to sassc-rails instead.

Good idea! Do you know if there's an impact on the existing code or can we just upgrade without other changes?

In other code I've upgraded without changes.

@wvengen you can upgrade to 2.5.1 for this :)
