Add Prometheus Metric for In-Progress Workflow Job Duration

[huseyinbabal]

This PR introduces a new Prometheus metric, github_workflow_job_in_progress_duration_seconds, to track the in-progress duration of workflow jobs in seconds. This metric provides real-time visibility into the duration of jobs that are currently running, complementing existing metrics like github_workflow_job_run_duration_seconds and github_workflow_job_queue_duration_seconds.

Changes:

• Added github_workflow_job_in_progress_duration_seconds as a prometheus.CounterVec with the following labels:
  • runs_on
  • job_name
  • organization
  • repository
  • repository_full_name
  • owner
  • workflow_name
  • head_branch
• Registered the new metric in the metrics.Registry.

Additional Context:

• The metric uses the same label structure as other workflow job metrics for consistency.

Fixes #4041
