unset GTIHUB_ACTION_REPOSITORY and GITHUB_ACTION_REF for non-repo based actions.

* add `workflow_dispatch`

* Add an environment variable to indicate which repository the currently running Action came from.

* Expose the Action ref as well.

* Move setting `github.action_repository` and `github.action_ref` to `ActionRunner.cs`.

* Don't set `action_repository` and `action_ref` for local Actions.
