To Reproduce

To execute the job, specify a runner provisioned by ARC in runs-on

Describe the bug

Previously, job_name was included in gha_completed_jobs_total and gha_started_jobs_total. However, the job_name value has been empty since approximately 19:00 (UTC) on 2025/6/9.

When checking the metrics with curl, they appear as follows:

gha_job_startup_duration_seconds_sum{event_name="",job_name="",job_result="",job_workflow_ref="XXXX",organization="XXXX",repository="XXXX"} 120

Describe the expected behavior

As stated in https://github.com/actions/actions-runner-controller/blob/master/charts/gha-runner-scale-set/values.yaml#L157, the job_name value is expected to be present, but currently it's empty.

The absence of job_name in metrics, preventing us from performing job-specific analysis, such as identifying which jobs are taking a long time to start up.
