Add actor property to WorkflowRun (PyGithub#2764)

The GitHub API [returns an `actor` field when listing workflow
runs](https://docs.github.com/en/free-pro-team@latest/rest/actions/workflow-runs?apiVersion=2022-11-28#list-workflow-runs-for-a-workflow)
but `WorkflowRun` does not include `actor`.

This PR adds the `actor` property of `NamedUser` type.

Not sure about field ordering conventions so just followed the API
response schema.
