helm chart multiBackupRepos volume storageclassname is invalid

reason:

postgres-operator-examples/helm/postgres/templates/postgres.yaml

Lines 62 to 64 in 26c6fba

	{{- if $repo.volume.backupsStorageClassName }}
	storageClassName: {{ .Values.backupsStorageClassName | quote }}
	{{- end }}

An incorrect value has been referenced in L63, i think it should be $repo.volume.backupsStorageClassName
