  Next steps:

  * Review the release notes:

      #{project.release_url}

  * Get someone to review and approve the release pull request:

      #{wait_for_non_nil(-> { project.release_pr_url }, max_attempts: 10, sleep_time: 0.5)}

  * Merge the pull request manually from the command line with the following
    commands:

      git checkout #{project.default_branch}
      git merge --ff-only #{project.release_branch}
      git push

  * Wait for the CI build to pass on the default branch and then release the
    gem with the following command:

      rake release:rubygem_push
