Fix error on rollback

[BClark88]

Context

#create_enum allows for if_not_exists and force options If no down migration is specifically created this will then cause an error on rollback I was able to replicate this in a basic rails app with the following migration:

class EnumTest < ActiveRecord::Migration[7.1]
  def change
    create_enum :my_enum, %w[foo bar baz], if_not_exists: true
  end
end

➜ enum-test git:(main) ✗ rails db:rollback --trace                                                                                                                                                                                                                                                          [24-05-28|13:05:55]

What's inside

Adds an optional unused arg to ActiveRecord::PostgresEnum::CommandRecorder. This allows rollbacks to be handled gracefully when options are passed in
