GitHub now has a new event of "dynamic" on workflow runs. I can't find any published docs, but looking at the data it appears to be dynamic runs of workflows for things like Dependabot, etc. The results is when GHWorkflowRun maps event field in getEvent() method to the GHEvent enum it ends up being UNKNOWN and logs a warning in the EnumUtils class that the value is unknown. DYNAMIC should be added to the GHEvent enum to minimize log warnings and add clarity for known (even if not published) possible values.
