If the plan is large then the step to comment it fails

[mission-lblaney]

Error: An error occurred trying to start process '/home/runner/runners/2.294.0/externals/node16/bin/node' with working directory '/home/runner/work/REPO_NAME/REPO_NAME'. Argument list too long

This step:

 - uses: actions/github-script@v6
        if: github.event_name == 'pull_request'
        env:
          PLAN: "terraform\n${{ steps.plan.outputs.stdout }}"
