Include SHA of test merge commit in PR generator for GitHub #623
Description
Component: Pull Request Generator
Request: Currently, when using the PR Generator with GitHub, we are provided with the head_sha. Additionally being provided with merge_commit_sha would be extremely useful.
Motivation: The default behavior of a lot of widely-used GHAs, such as actions/checkout and docker/metadata-action, is to use the test merge commit sha rather than the head sha. Providing this value would mean users have a way of working with PR generator without having to override this behavior throughout their stack, and seeing predicatable values being propagated everywhere.
I'm unfamiliar with GitLab and Gitea but I think based on some quick searching that they too create test merge commits, but at least for GH, it seems like it would require a change
