Rubocop config is not setup to actually lint the library

When attempting to lint changes on my Fork in hope of upstream merges, I noticed the config does not seem to be up to date and matching the lockfile's Rubocop version.

Namely you see a host of issues:

.ruby-style.yml:240: `Style/IfWithSemicolon` is concealed by line 752
.ruby-style.yml:245: `Style/InfiniteLoop` is concealed by line 762

(obsolete configuration found in .ruby-style.yml, please update it)
obsolete parameter `Whitelist` (for `Style/TrivialAccessors`) found in .ruby-style.yml
`Whitelist` has been renamed to `AllowedMethods`.

Which tend to be:

1. Lots of linter name/config changes or replacements
2. Rules for non-included rubocop-rails that do not apply anyway
3. The config itself basically excludes most of the library directory structure

Did not want to put these changes into my branch though, as the patch ends up being quite large and not sure what the appetite for that is 0001-Fix-Rubocop.patch
