Fixed the Indent length for CronJob

[chriskery]

What did I change:

Change CronJob indent to 12 .

detailed:

If I put args in the CronJob like below:

apiVersion: batch/v1
kind: CronJob
metadata:
  name: cron-job
spec:
  schedule: "* * * * *"
  jobTemplate:
    spec:
      template:
        spec:
          containers:
......
              args:
              - --leader-elect

And run pkg/app/app_e2e_test.go, an error occurs:

  app_e2e_test.go:58: 
            Error Trace:    /Users/yuewenchen/GolandProjects/helmify/pkg/app/app_e2e_test.go:58

            Test:           TestApp
--- FAIL: TestApp (0.06s)

If we checks the outputs of helm, we can see that the problem is caused by incorrect args indentation :

> helm template  app . --debug
---
# Source: app/templates/cron-job.yaml
apiVersion: batch/v1
kind: CronJob
spec:
  jobTemplate:
    spec:
      template:
        spec:
          containers:
          - args:
        - --leader-elect
