To Reproduce

1. enable listener metrics
2. try to check acquired or available metrics from the metrics path

Describe the bug

https://github.com/actions/actions-runner-controller/blob/master/docs/adrs/2023-05-08-exposing-metrics.md?plain=1#L175 says that there should be available_jobs & acquired_jobs metrics exposed. However, for some reason these are disabled in code? https://github.com/actions/actions-runner-controller/blob/3e4201ac5f6c6d172a19b580154eaf5abf24a2ca/cmd/githubrunnerscalesetlistener/metrics.go#L54-L71

Describe the expected behavior

expected behaviour is that I could see values of these metrics in my prometheus.

Now I can see these only in pod logs, which makes it pretty difficult to make alerts based on metrics.

I'm considering filing a separate issue but job_queue_duration_seconds is also missing and I'm not sure why. It is quite relevant to a situation we had where the Listener stops responding and jobs are no longer picked up. We don't currently have a good way of monitoring when jobs no longer are being picked up.
