Rubinius builds will no longer be provided

* This reverts commit 35f0af38a7.
* It fails for some cases like Ruby <= 2.2 and on some RubyInstaller builds,
  see https://github.com/ruby/setup-ruby/issues/98#issuecomment-723468255
* Most users will use Bundler to install rake, and that already works fine.

 This caching speeds up installing gems significantly and avoids too many requests to RubyGems.org.  
 It needs a `Gemfile` (or `$BUNDLE_GEMFILE` or `gems.rb`) under the [`working-directory`](#working-directory).  
 If there is a `Gemfile.lock` (or `$BUNDLE_GEMFILE.lock` or `gems.locked`), `bundle config --local deployment true` is used.
 
 To perform caching, this action will use `bundle config --local path vendor/bundle`.
