title: Download terraform plan as a file from GitHub
body: <p>I am working on a GitHub Actions pipeline where I am creating a terraform plan and then after downloading and reviewing the plan in a file authentication the apply stage. Everything is working smoothly, I get a plan that I am then saving as a tt file using the <code>'out'</code> flag, but I am not able to figure out how to download the plan file from the runner to my local machine or even save it as an artifact. Please help me out if there is a workaround.</p>
