Cancel in progress Github runners on subsequent push

[cwperks]

Description

This PR will cancel any in progress runners if a contributor pushes another commit. This helps particularly in cases where a contributor pushes a CHANGELOG entry after opening a PR when the PR number is known. It helps to conserve runners since there are only a limited number in a pool.
