Overview of changes:
Fixes #1816
Anything you'd like to highlight / discuss:
The update is such that if multiple commits are synchronized on an open PR, the queued & in-progress workflow runs will be canceled (in favor of the workflow run for the latest commit). However, push events should not be affected by this due to the concurrency group setting. This is just to be extra safe such that all push to master triggers and run the workflow to completion.
The side-effect of this is that an email will be sent out to inform that a workflow is canceled.
Testing instructions:
