  * d/patches/0028-Fix-test-for-rouge-3.22.patch: Add patch.
    - Relax test to work with ruby-rouge 3.22 too.
  * d/patches/series: Enable new patch.

Update to upstream version '3.9.0+dfsg'
with Debian dir 512017f4e1bb01fa7a962c3a310eda9d9dab5d6d

  * d/ruby-tests.rake: Enable plugin manager tests.
  * d/patches/0025-skip-plugin-tests-requiring-bundler.patch: Add patch.
    - Skip plugin manager test relying on bundler and upstream's Gemfile.

  * d/patches/0024-use-platforms-in-gemfile.patch: Add patch.
    - Don't use :install_if in default Gemfile and use :platforms instead (see
      https://lists.debian.org/debian-ruby/2020/04/msg00062.html).
  * d/patches/series: Adjust accordingly.

  * d/ruby-tests.rake: Enable the new command test based on the
    AUTOPKGTEST_TEST_NEW_COMMAND environment variable.
  * d/tests/control: Add another test to run test_new_command.rb.

  * d/ruby-tests.rake: Enable coffeescript tests based on the
    AUTOPKGTEST_TEST_COFFEESCRIPT environment variable.
  * d/tests/control: Change to run gem2deb-test-runner as command. By setting
    an enviromnent variable we set the tests to load in d/ruby-tests.rake.

Remove all attempts to run test_new_command.rb. It always fails when run the
first time and then succeeds. Maybe this is a root issue and we need to run
the test as root?

  * d/patches/0023-drop-custom-profile-simplecov.patch: Add new patch.
    - This custom profile somehow interfers with the tests and leads to errors.
      Worse the errors are not shown. So drop it.
  * d/patches/series: Adjust accordingly.

  * d/patches/0022-escape-regex-characters-in-match.patch: New patch.
    - Convertible tests try to match some paths to output. Because our version
      contains a plus sign it must be escaped properly.
  * d/patches/series: Adjust accordingly.
