🧪 So...... I think I might've crossed the Dr. Ian Malcom line here..... but I can now do high-level testing of GitHub Actions in Pants...

experimental_test_shell_command(
    name="Test auto-cherry-picker prereqs",
    command="./act workflow_dispatch -W .github/workflows/auto-cherry-picker.yaml -j prerequisites --input PR_number=17295 --env GITHUB_REPOSITORY=pantsbuild/pants",
    execution_dependencies=["//build-support/bin/act:bundled-act"],
    workdir="/",
    timeout=120,
)

Now I know I don't have broken YAML and my code executes reasonably well...
