To Reproduce

In k8s mode using the container hook template, you need to request more cpu,memory,storage etc. than the resource quota. For example:

1. Define resource quota with hard limit for cpus/memory e.g. 8 cpus

apiVersion: v1
kind: ResourceQuota
metadata:
  name: arc-runners-quota
  namespace: arc-runners
spec:
  hard:
    requests.cpu: "8"

2. Set up ARC with autoscalingrunnerset k8s mode with a container hook template

apiVersion: actions.github.com/v1alpha1
kind: AutoscalingRunnerSet
metadata:
  name: self-hosted-k8s
  namespace: arc-runners
spec:
...
  template:
    spec:
      containers:
      - name: runner
        resources:
          requests:
            cpu: "0"
        env:
        ...
        - name: ACTIONS_RUNNER_CONTAINER_HOOK_TEMPLATE
          value: /home/runner/workflow-pod-config/workflow-pod-config.yaml
        ...
        volumeMounts:
        ...
        - mountPath: /home/runner/workflow-pod-config
          name: workflow-pod-config
      volumes:
      ...
      - name: workflow-pod-config
        configMap:
          name: workflow-pod-config
          items:
            - key: workflow-pod-config.yaml
              path: workflow-pod-config.yaml
...
---
apiVersion: v1
kind: ConfigMap
metadata:
  name: workflow-pod-config
  namespace: arc-runners
data:
  workflow-pod-config.yaml: |
    apiVersion: v1
    kind: PodTemplate
    metadata:
      labels:
        app: runner-pod-template
    spec:
      containers:
      - name: $job
        resources:
          requests:
            cpu: "5"

3. Run a workflow with two jobs matching the autoscalingunnerset name

on:
  push:
    branches: [ main ]
jobs:
  job1:
    runs-on: self-hosted-k8s
    container:
      image: ubuntu:22.04
    steps:
    - run: sleep 60
  job2:
    runs-on: self-hosted-k8s
    container:
      image: ubuntu:22.04
    steps:
    - run: sleep 60

You can also do this with a single job that goes over the resource quota. But above is more likely scenario.

Describe the bug

In the example provided, one job will run successfully, the other will fail when trying to create the workflow pod as the resource quota is temporarily being exceeded.

In general, jobs fail due to quota being temporarily being exceeded.

Describe the expected behavior

In the example provided, one job should run at a time and queue properly and complete one after the other. Leading to a successful build.

In general, when quota is temporarily exceeded, we should try again after a while preferably through a queue implementation. Though it is also bit stupid that the runner starts even when there is no room for the workflow pod but I am not sure what could be done without changing the architecture of ARC a lot.

Additional Context

This can be considered separate issue than https://github.com/actions/actions-runner-controller/issues/3629 as I believe the code needs to change in a different spot and it behaves a little bit differently. This is why I created two issues.
