rubocop: In-line Style/HashAsLastArrayItem disablement

- We want to move away from `Excludes:` in the main `.rubocop.yml` config file
  containing full file paths, because it's hard to track whether they're still
  necessary or not (and other occurrences in the files that you might
  legitimately want to improve are unaccounted for).
