Plugin restore doesn`t work due to "no restore jobs hook capability" (plugin version v0.6.0, sidecar image version v.0.5.0), cnpg 1.27

I am testing restore from an S3 bucket with the plugin, using the documented restore procedure, from a a working backup archive, cluster and objectstore spec available in [this issue](https://github.com/cloudnative-pg/plugin-barman-cloud/issues/502) if needed.

manifest:

```
# Source: obfuscated-db/templates/restoreTest.yaml
apiVersion: postgresql.cnpg.io/v1
kind: Cluster
metadata:
name: obfuscated-db-stage-restore-test
spec:
instances: 1
imagePullPolicy: IfNotPresent
bootstrap:
recovery:
source: source
externalClusters:
- name: source
plugin:
name: barman-cloud.cloudnative-pg.io
parameters:
serverName: obfuscated-db-stage
ObjectName: obfuscated-db-stage-backup
storage:
size: 5Gi
```

# k logs obfuscated-db-stage-restore-test-1-full-recovery-8vg2f

失敗は internal/cmd/manager/instance/restore/restore.go:79 と cmd.go:101 に到達します。まず plugin v0.6.0 と sidecar v0.5.0、restore manifest、ログを比較し、動作するセットアップには issue #502 を使用します。文書化された restore 手順が「no plugin supports the restore job hooks capability」エラーなしで完了すれば完了です。
