Add channel for rubocop 1.63.5

Hi, I'd like to request a channel for the latest rubocop, [1.63.5](https://rubygems.org/gems/rubocop/versions/1.63.5)

The latest channel currently available is [1.56.3](https://hub.docker.com/layers/codeclimate/codeclimate-rubocop/rubocop-1-56-3/images/sha256-160115e35fb520971ce10c14c756f56218137a4a9d74901ac80ade5aea237d0d?context=explore)
