The continuous benchmarks site could have a commit id

At https://tfb-status.techempower.com the runs id doesn't seem to match to a git commit, so it would be very helpful to have that either in details or on the main page so that we can know if the run is using our latest changes.

Thanks

Addressed by #3257, but I think no new results have been captured since that was merged.
