Toolbox podLabels are not propagated to backup instances

Summary

It seems the gitlab.toolbox.podLabels are not propagated to backup instances of the toolbox. These instances are created by the gitlab.toolbox.cron.* settings. The difference in configuration can be observed in https://gitlab.com/gitlab-org/charts/gitlab/-/blob/v8.7.4/charts/gitlab/charts/toolbox/templates/deployment.yaml?ref_type=tags#L25-28 and https://gitlab.com/gitlab-org/charts/gitlab/-/blob/v8.7.4/charts/gitlab/charts/toolbox/templates/backup-job.yaml?ref_type=tags#L38-40

Steps to reproduce

Configure the spec.chart.values.gitlab.toolbox.podLabels property and observe the labels aren't present on backup instances of the toolbox.

Configuration used

spec:
  chart:
    values:
      gitlab:
        toolbox:
          backups:
            cron:
              enabled: true
              schedule: 0 3 * * *
          ...  
          podLabels:
            some-pod-label: 'true'

Current behavior

The some-pod-label label is not present on backup instances of the Toolbox.

Expected behavior

The some-pod-label label is present on backup instances of the Toolbox.
