Rails/EnumSyntax autocorrection causes deprecation warning on Ruby 2.7

[r7kamura]

Rails/EnumSyntax does the following autocorrection:

rubocop-rails/spec/rubocop/cop/rails/enum_syntax_spec.rb

Lines 115 to 124 in 210f42e

	it 'autocorrects' do
	expect_offense(<<~RUBY)
	enum status: { active: 0, archived: 1 }
	^^^^^^^^^^^^^^^^^^^^^^^^^^ Enum defined with keyword arguments in `status` enum declaration. Use positional arguments instead.
	RUBY
	expect_correction(<<~RUBY)
	enum :status, { active: 0, archived: 1 }
	RUBY
	end

However, if you run the autocorrected code in Ruby 2.7, you will get a deprecated warning about the usage of keyword arguments, depending on the warning options (e.g. -W:deprecated) and ruby versions.

Expected behavior

No warnings should be reported after autocorrection.

In other words, code that originally did not have a deprecation warning should not be changed by autocorrect to a state where a deprecation warning is issued.

Actual behavior

The following warning is reported after its autocorrection:

warning: Using the last argument as keyword parameters is deprecated; maybe ** should be added to the call
/home/r7kamura/.rbenv/versions/2.7.8/lib/ruby/gems/2.7.0/gems/activerecord-7.1.4/lib/active_record/enum.rb:216: warning: The called method `enum' is defined here

Steps to reproduce the problem

You can verify that this warning is output by running the following code in Ruby 2.7:

# frozen_string_literal: true

require "bundler/inline"

gemfile do
  source "https://rubygems.org"

  gem "rails"
  gem "sqlite3", "< 1.7" # sqlite3 1.7+ doesn't support Ruby 2.7.
end

require "active_record"

ActiveRecord::Base.establish_connection(adapter: "sqlite3", database: ":memory:")

ActiveRecord::Schema.define do
  create_table :posts, force: true do |t|
    t.integer :status
  end
end

Warning[:deprecated] = true

class Post < ActiveRecord::Base
  enum :status, { active: 0, archived: 1 }
end
