 Setting a controller repository for variant analysis

 When you run variant analysis, the analysis is run entirely using GitHub Actions. You don't need to create any workflows, but you must specify which GitHub repository the CodeQL extension should use as the "controller repository." Controller repositories can be empty, but they must have at least one commit and the ``GITHUB_TOKEN`` must have "Read and write permissions" when running workflows. For more information, see "`Managing GitHub Actions settings for a repository <https://docs.github.com/en/repositories/managing-your-repositorys-settings-and-features/enabling-features-for-your-repository/managing-github-actions-settings-for-a-repository#setting-the-permissions-of-the-github_token-for-your-repository>`__."
