Subject: [PATCH] Fix concurrent-ruby version in Ruby 2.5/2.6 CI

active_support/logger_thread_safe_level.rb in Rails 6.1
references Logger without requiring it, which only worked
because concurrent-ruby was requiring it.  concurrent-ruby
1.3.5 dropped the logger require, which broke active_support.
