Proxy doesn't support keyworad argument of Ruby 3.0

[ashie]

Example test code

require 'test/unit/rr'

class Klass
  def write(txt, silent: true)
    puts(txt) unless silent
  end
end

class TestKlass < Test::Unit::TestCase
  test "write" do
    c = Klass.new
    mock.proxy(c).write("write", silent: false).once
    c.write("write", silent: false)
  end
end
