feat: Add Commit Info

[davelosert]

This PR introduces two things:

1. Feature-wise, I've added an extraction for the Head-Commit-SHA (for pull requests and workflow runs) or the action SHA (for all other events) to be added to the report for user to be able to easier identify for which commit of a PR the current report is valid
2. I did a lot of refactoring:
   1. I put all functionality related to finding the current PR-Number into the same location (was previously split out also in the the issue-comment-functions)
   2. I am now using the workflow_run-information directly from the event payload - previously, I was doing an HTTP Request to get the Workflow-Payload (which was unecessary)
   3. I added LOTS of tests, bumping up coverage by orders of magnitude here.
   4. Made this very action generate a comparison report so I see (and also test) this feature regularly
   5. Removed the mock-test-reporting as this is now covered enough by automatic tests
