Feature Request: Show PR commit number

[gwatts]

Description

Some PRs I review have multiple commits (if a submitter has been kind enough to split their work up into small logical chunks), and I step through them one at a time. It would be incredibly useful to know I'm reviewing "commit 3/10" of a 10 commit PR

In the screenshot below i'm actually on commit 8 of 10 but have no way of knowing right now short of hitting next a couple more times

i guess i can also use the "Changes from 1 commit" dropdown on the left to see where i'm at.. not sure i realized that till this moment!
