[SRE-801] Update Ruby style for 2022

[theRobinator]

The config here is the result of a meeting where we all voted for each deviation from the default style guide.

Because each codebase uses inheritance over https, this PR needs to sit open until all the relevant codebases can be updated.

To add this to your codebase:

1. Clone this repo and check out this branch.
2. cd into your project's directory.
3. Run the applystyles.sh script from this PR via /path/to/applystyles.sh
4. If the script finishes with a green line saying "no offenses", you're good! Otherwise, fix any errors that appear.
   • This may involve updating your versions of Rubocop to match the ones in API.
   • Some projects require the defunct blue_steel gem, which you can safely remove.
   • If any offenses are printed during the script's final rubocop run, you will need to manually fix them and re-run bundle exec rubocop -P to see if they disappear.
5. Run your unit tests just in case.
6. Make sure your .ci file has a Rubocop stage like the one in API. Optionally, you can remove the stuff about reports.
