Proper logging of CI benchmarks

## 🚀 Feature

It would be better for the CI benchmarks: https://github.com/Lightning-AI/lightning-thunder/blob/main/.github/run-benchmark-as-lit-jobs.py are logged somewhere easily observable and accessible.

Start with .github/run-benchmark-as-lit-jobs.py and trace how CI benchmark output is currently produced. Determine an accessible place for the benchmark logs and verify that a CI benchmark run makes its results observable there; the issue names no test or validation command.
