This commit fixes two types of Rubocop failures seen only with Ruby 3.2:

* Style/ArgumentsForwarding: As explained in
  https://www.rubydoc.info/gems/rubocop/RuboCop/Cop/Style/ArgumentsForwarding,
  in Ruby 3.2, anonymous args/kwargs forwarding has been added. This cop can
  be disabled by setting `UseAnonymousForwarding: false`.

* Lint/RedundantRequireStatement: As explained in
  https://www.rubydoc.info/gems/rubocop/RuboCop/Cop/Lint/RedundantRequireStatement,
  `require 'set'` is no longer needed in Ruby 3.2. But since we still
  need to support Ruby 3.1 and earlier, disable this cop on `require 'set'`
  lines.
