Backup CronJob is missing object_store secret

Summary

The task-runner-backup CronJob is missing the object_store secret, so backups fail.

Steps to reproduce

Enable the new object_store configuration (that might even not be necessary) and the backup CronJob, wait for it to trigger.

Configuration used

global:
  appConfig:
    object_store:
      enabled: true
      connection:
        secret: gitlab-object-store
        key: connection

    backups:
      bucket: backups.gitlab.example.com

gitlab:
  task-runner:
    backups:
      cron:
        enabled: true
        schedule: "@every 24h"

      objectStorage:
        config:
          secret: gitlab-object-store
          key: s3cmd-config

Current behavior

/usr/lib/ruby/2.6.0/psych.rb:577:in `initialize': No such file or directory @ rb_sysopen - /etc/gitlab/objectstorage/object_store (Errno::ENOENT)
	from /usr/lib/ruby/2.6.0/psych.rb:577:in `open'
	from /usr/lib/ruby/2.6.0/psych.rb:577:in `load_file'
	from (erb):36:in `<main>'
	from /usr/lib/ruby/2.6.0/erb.rb:901:in `eval'
	from /usr/lib/ruby/2.6.0/erb.rb:901:in `result'
	from /scripts/set-config:22:in `block in <main>'
	from /scripts/set-config:18:in `each'
	from /scripts/set-config:18:in `<main>'
Begin parsing .erb files from /var/opt/gitlab/templates
Writing /srv/gitlab/config/cable.yml
Writing /srv/gitlab/config/resque.yml
Writing /srv/gitlab/config/gitlab.yml

Then the backup job fails.

Expected behavior

The backup should work! :-)
