Webhook autoscaling does not work as expected.

[Kananideel]

Concern:
We have seen a pattern where the auto scaling does not spin up pods as and when needed.
Jobs which request for self-hosted runners are in waiting state for 15-20 minutes on an average, even when the auto-scaling is in place.

We currently have runners based on summerwind/actions-runner:latest

Datadog Shows that we have an average of 30 pods running.
Auto Scaling has been set to 100 pods.
2 webhook Deployments are in place. (actions-runner-controller-github-webhook-server)
Arc version is on Latest Version, 0.23.3.

Steps to reproduce the problem.
execute multiple(30) workflows which internally has multiple jobs(3) calling the same runner.

Expected behavior:-
The runner should auto scale and pod should be allocated to jobs quickly.

Current behavior:-
The workflow jobs are in pending state for an average 15-20 minutes.
