In run-script-step, the _temp directory was being copied to the workflow pod, but the _github_home and _github_workflow directories were not being moved from their temporary location to the /github directory structure where they are expected by GitHub Actions. This caused event.json to be missing at /github/workflow/event.json, breaking actions that depend on GITHUB_EVENT_PATH. The fix adds a setup step that copies _github_home and _github_workflow from /__w/_temp/ to /github/ after copying the temp directory to the pod, matching the behavior of run-container-step and prepareJobScript. Uses cp -r instead of symlinks to avoid symlink validation errors when copying files back from the pod to the runner.
