What does this MR do?

Updates Code Climate to 0.85.1.

The changes from 0.83.0 to 0.85.1 are:

• [NEW] Add rubocop-0-64 channel
• [NEW] Add rubocop-0-65 channel
• [NEW] Add rubocop-0-66 channel
• [FIX] No longer warn for using ignore_fingerprints in .codeclimate.yml
• [FIX] Don't turn on debug mode when CODECLIMATE_DEBUG is set but blank
