[conan.io/center] Capture/Show git commit corresponding to recipe revision

### What is your problem/feature request?

I needed to do a maintenance release of an older product build. The fix required a change to a 3rd party library that was pulled from conan center. This required me to vendor the recipe. Because I wanted to change as little as possible, I wanted to get the exact recipe used for the recipe revision I was locked to. I was able to recreate this from the cache of my previous package version, but it is missing some stuff (e.g. testing). It would have been useful if I could have looked up the git commit corresponding to that recipe revision so I could browse the repository at that commit. Seems like you could capture that at the time the recipe is published.
