Adding GitHub Audit Log Extractor

[rreddy2]

Summary of Change

Adding an Audit Log Extractor for the GitHub plugin. I was able to test this locally and it seems to work as expected! As of now, we will support filtering the audit log based on different action(s). There may be some room to add more filtering based on time as well, but at the moment I don't think it'll be required.
