Want to know expected and actual commit hashes

[zaki-yama]

Is your feature request related to a problem? Please describe.

When I tried to introduce reg-suit, I sometimes thought that I want to check if reg-suit had chosen 2 commits correctly for expected and actual results.
(Especially, I wondered if reg-keygen-git-hash-plugin picked up the "expected" commit from base branch correctly)

Describe the solution you'd like

It'd be nice if I can check expected and actual commits via PR comment or report.

Describe alternatives you've considered

Now I can archive this by seeing the log.
If there're any other means, please tell me.

For both of the "publisher" plugins, the "actual" commit is in the report URL, so that's easily accessible.

The "expected" commit isn't printed anywhere conveniently though (except in logs); that would definitely be nice to have!
