Update to the Flog plugin: support Ruby 3.1 syntax

Code Climate on May 30, 2023

This week we deployed an update to the codeclimate-flog plugin!

The plugin’s ruby_parser gem was updated to version 3.20.0, which supports Ruby 3.1 syntax.

If you use Flog and want to run it on Ruby 3.1+ code, be sure to enable either the flog-4-6-6 or beta channel in your .codeclimate.yml config file, like so:

plugins:
  flog:
    enabled: true
    channel: flog-4-6-6

Thanks to Fonji on Github for reporting the issue!
