Please expose checkRun "runs-on" data in API/Event

We wish to monitor our self-hosted runners. To do that we are listening to check_run events.
But the only place where the “runs-on” info is available is as part of the workflow file which makes it very hard to correlate between the check_run and its targeted hosts.

We’re currently working on exposing the label info as part of webhooks that are emitted when the job is queued, started, and completed. They should be available soonish.
