Improve Style/RedundantParentheses cop for lambdas

Actual behavior

I have the following code:

class Post < ApplicationRecord
  scope :published1, (lambda do
    foo
  end)

  scope :published2, (-> { bar })
end

Terminal:

ydakuka@yauhenid:~/Work/project$ bin/rails_docker rubocop app/models/post.rb 
Inspecting 1 file
.

1 file inspected, no offenses detected

Rubocop

And for the next examples there is a wrong indentation, but rubocop does not detect any offences.

class User < ApplicationRecord
  scope :published3, (lambda do
                        baz
                      end)

  scope :published4, (
        -> { car }
      )
end
