Facter-ng was the name given to the facter 4 gem that shipped in the puppet 6 stream. Now that 6 is EOL we should delete references to facter-ng from facter#main branch.
.rubocop.yml
./bin/facter-ng
./agent/facter-ng.gemspec
./agent/lib/facter-ng.rb
./acceptance/tests/options/help.rb
Also update CJC and remove facter-ng jobs & promotions.
