feat(activerecord): Add types for ActiveRecord::Relation#reorder and ActiveRecord::Relation#unscope (#970)

Similar to #858, I add types to both interfaces and modules.
Because interfaces are still used by some applications and gems.

e.g.

- https://github.com/ksss/orthoses-rails/blob/v1.13.2/lib/orthoses/active_record/relation.rb#L40
- https://github.com/ksss/orthoses-rails/blob/v1.13.2/lib/orthoses/active_record/relation.rb#L52
- https://github.com/kaigionrails/conference-app/blob/331d122645f4c046702998ddec4b9f2e194fa5e1/sig/rbs_rails/app/models/speakers_talk.rbs#L2

added method implementations are below

- https://github.com/rails/rails/blob/v8.1.1/activerecord/lib/active_record/relation/query_methods.rb#L743-L757
- https://github.com/rails/rails/blob/v8.1.1/activerecord/lib/active_record/relation/query_methods.rb#L773-L809
