Replacing sass-rails with sassc-rails

[MikeRogers0]

Following up for #3072

This replaces sass-rails with sassc-rails, as sass-rails is now just a wrapper for sassc-rails (as updated in rails/sass-rails#424 )

It looks like CI is failing, but I'm seeing the same error locally in the master branch. @sferik can you shed some light on how I can fix? :)

FYI: Change
s/10/11/ on line 44 and
s/20/21/ on line 45
in inspec/integration/basic/dashboard/rails_admin_basic_dashboard_spec.rb
makes my local build green. Now figure out why. My run line:

bundle exec rspec ./spec/integration/basic/dashboard/rails_admin_basic_dashboard_spec.rb:36

Failure was an timing issue, that spec fails during specific window of time in UTC.

Thank you @mshibuya, that has fixed most the CI issues I was seeing :) Though there appear to be a coverage drop in Ruby: jruby-9.2.6.0 Gemfile: gemfiles/rails_5.2.gemfile CI_ORM=mongoid causing a failure :/

[mshibuya]

Lowering coverage-threshold to 90.05 is acceptable, since this change should not harm test exhaustivity.

@mshibuya Minimum coverage updated 👍 :)

Yay all green 🎊

Merged in, thanks ❤️
