Fix error in Action Runner System when computing replicas

Checks

• I've already read https://github.com/actions/actions-runner-controller/blob/master/TROUBLESHOOTING.md and I'm sure my issue is not covered in the troubleshooting guide.
• I'm not using a custom entrypoint in my runner image

Controller Version

0.17.3

Helm Chart Version

0.17.3

CertManager Version

No response

Deployment Method

Helm

cert-manager installation

Yes installed correctly

Checks

• This isn't a question or user support case (For Q&A and community support, go to Discussions. It might also be a good idea to contract with any of contributors and maintainers if your business is so critical and therefore you need priority support
• I've read releasenotes before submitting this issue and I'm sure it's not due to any recently-introduced backward-incompatible changes
• My actions-runner-controller version (v0.x.y) does support the feature
• I've already upgraded ARC (including the CRDs, see charts/actions-runner-controller/docs/UPGRADING.md for details) to the latest and it didn't fix the issue
• I've migrated to the workflow job webhook event (if you using webhook driven scaling)

Describe the bug

he specific error message encountered is: Action Runner System - Could not compute replicas: {"horizontalrunnerautoscaler": "actions-runner-system/k8s-runners-autoscaler", "error": "listing queued workflow runs: failed to list workflow runs: GET https://github./actions/runs?per_page=100&status=queued: 404 Not Found []"}
• The error is preventing the Action Runner System from properly listing queued workflow runs, resulting in the inability to compute replicas accurately.

Describe the expected behavior

I should be able to GET the API call

Additional Context

No source file, test, or reproducible setup is identified. Start by tracing the horizontal runner autoscaler's queued-workflow-runs lookup for the GitHub Actions API request, then verify that queued runs can be listed and replicas are computed without the reported 404.
