Node affinity and node selector fix

[scientress]

I need to use nodeAffinity or nodeSelector to limit the nodes to the correct architecture in a multi architecture cluster. While I tried to do that I noticed the the hook-verify-mongodb-version.yaml templates currently produces invalid yaml if you provide either.

Example of malformed yaml output by the template:

# https://kubernetes.io/docs/concepts/workloads/pods/
apiVersion: batch/v1
kind: Job
metadata:
  name: 'rocketchat-rocketchat-pre-upgrade'
  annotations:
    "helm.sh/hook": pre-upgrade
    "helm.sh/hook-delete-policy": hook-succeeded
spec:
  backoffLimit: 5
  parallelism: 1
  completions: 1
  template:
    metadata:
      name: 'rocketchat-rocketchat-pre-upgrade'
      labels:
        app.kubernetes.io/managed-by: "Helm"
        app.kubernetes.io/instance: "rocketchat"
        helm.sh/chart: "rocketchat-6.25.1"
    spec:
      restartPolicy: OnFailure
      tolerations:
        - effect: NoSchedule
          key: special
          operator: Equal
          value: highcpu
      nodeSelector:
              beta.kubernetes.io/arch: amd64
        other.label: foo
      affinity:
              nodeAffinity:
          requiredDuringSchedulingIgnoredDuringExecution:
            nodeSelectorTerms:
            - matchExpressions:
              - key: beta.kubernetes.io/arch
                operator: In
                values:
                - amd64

The error is caussed by an incorrect ussage of the indent filter. I fixed this and also improved the indentation of nodeAffinity and nodeSelector in the Deployments.

Fixed output of the tamplate with the purposed changes:
