customize_gemfiles drops error message

[Antronin]

I added the following code to the Appraisals file, according to the documentation:

customize_gemfiles do
  {
    single_quotes: true,
    heading: <<~HEADING
      frozen_string_literal: true

      `%<gemfile>s` has been generated by Appraisal, do NOT modify it or `%<lockfile>s` directly!
      Make the changes to the "%<appraisal>s" block in `Appraisals` instead.
    HEADING
  }
end

The result of appraisal generate:

Without the block it works perfectly.

I also found the problem, but I'm not sure what to do with it. In the gem's 2.5.0 version, the file lib/appraisal/appraisal_file.rb it contains this from line 37:

    def customize_gemfiles(&_block)
      Customize.new(yield)
    end

This creates the problem, as it should be correct:

    def customize_gemfiles(&_block)
      Customize.new(**yield)
    end

Strangely enough, in the main branch, it is correctly written in the repo, but the gem contains the wrong code.
