chore(gha-runner-scale-set): update indentation of initContainers

[kahirokunn]

When setting dind and initContainers with values like the following, the following error occurs:

Error: UPGRADE FAILED: YAML parse error on gha-runner-scale-set/templates/autoscalingrunnerset.yaml: error converting YAML to JSON: yaml: line 49: did not find expected key

containerMode:
  type: "dind"
template:
  spec:
    initContainers:
    - name: kube-init
      image: ghcr.io/actions/actions-runner:latest
      imagePullPolicy: IfNotPresent
      command: ["sudo", "chown", "-R", "1001:123", "/home/runner/_work"]
      volumeMounts:
      - name: work
        mountPath: /home/runner/_work

When outputting with the debug option, the indentation was shifted as follows:

      initContainers:
      - name: init-dind-externals

        image: quay.io/kahirokunn/actions-runner:latest
        command: ["cp"]
        args: ["-r", "-v", "/home/runner/externals/.", "/home/runner/tmpDir/"]
        volumeMounts:
          - name: dind-externals
            mountPath: /home/runner/tmpDir
        - command:
          - sudo
          - chown
          - -R
          - 1001:123
          - /home/runner/_work
          image: quay.io/kahirokunn/actions-runner:latest
          name: kube-init
          volumeMounts:
          - mountPath: /home/runner/_work
            name: work

Therefore, in this modification, the indentation will be corrected as follows:

  initContainers:
  - name: init-dind-externals
    image: ghcr.io/actions/actions-runner:latest
    command: ["cp"]
    args: ["-r", "-v", "/home/runner/externals/.", "/home/runner/tmpDir/"]
    volumeMounts:
      - name: dind-externals
        mountPath: /home/runner/tmpDir
  - command:
    - sudo
    - chown
    - -R
    - 1001:123
    - /home/runner/_work
    image: ghcr.io/actions/actions-runner:latest
    name: kube-init
    volumeMounts:
    - mountPath: /home/runner/_work
      name: work

Can you please write a test to cover this scenario?
