feat(performance): add benchmark step to CI workflow

Add a new 'Benchmark' job in the GitHub Actions workflow to run
performance tests and generate graphs. Save the test report as
an artifact in the Earthfile. The job runs on 'github-001' and
triggers on PRs labeled 'benchmarks' or on the main branch.
