Cop to check "Deprecate defining enums with keywords args"

[guillaumebriday]

Is your feature request related to a problem? Please describe.

When upgrading my app to Rails 7.2.0rc1, I got this deprecation warning:

DEPRECATION WARNING: Defining enums with keyword arguments is deprecated and will be removed
in Rails 8.0. Positional arguments should be used instead:

See: https://sparkrails.com/rails-7/2024/02/13/rails-7-deprecated-enum-with-keywords-args.html
And: rails/rails#50987

Describe the solution you'd like

That would be cool to have a cop that ensure the new syntax is used:

class Function > ApplicationRecord
  # BAD
  enum color: [:red, :blue],
       type: [:instance, :class]

  # GOOD
  enum :color, [:red, :blue]
  enum :type, [:instance, :class]
end

Thank you in advance!
And thanks a lot for your awesome work on Rubocop 🙏
