Disable Rails/PluckId cop by default

This cop was originally disabled with the original rubocop import: standardrb@71e48d5#diff-da3213a24b350fa386ff3bab0d6b239112408c3fe4f986cbd9d5236f7e0b61e4R458-R463

It was subsequently enabled during a mass enable commit: standardrb@24bc50f#diff-da3213a24b350fa386ff3bab0d6b239112408c3fe4f986cbd9d5236f7e0b61e4R248-R249

As discussed on this issue, the cop is unsafe by default and frequently gets false positives: rubocop/rubocop-rails#301

It is disabled by default in most recent rubocop release, for same reasons: https://github.com/rubocop/rubocop-rails/blob/v2.25.0/config/default.yml#L746-L751

Discussion of why to disable on: standardrb#31
