need a proper way to change the bucket

Good day!

I tried to make the next experiment.

I had a working ObjectStore with a proper schedule.

```yaml
apiVersion: postgresql.cnpg.io/v1
kind: ScheduledBackup
metadata:
name: keycloakdb-daily
namespace: keycloak
spec:
backupOwnerReference: self
cluster:
name: keycloakdb
method: plugin
pluginConfiguration:
name: barman-cloud.cloudnative-pg.io
schedule: 0 2 * * *
```

```yaml
apiVersion: barmancloud.cnpg.io/v1
kind: ObjectStore
metadata:
name: keycloak
namespace: keycloak
spec:
configuration:
data:
compression: gzip
jobs: 2
destinationPath: s3://[mybucketname]/
endpointURL: https://storage.yandexcloud.net
s3Credentials:
accessKeyId:
key: AWS_ACCESS_KEY_ID
name: s3-yandex
secretAccessKey:
key: AWS_SECRET_ACCESS_KEY
name: s3-yandex
wal:
compression: zstd
maxParallel: 8
```

Now I want to change:
- bucketname to another one
- and appropriately change the `AWS_ACCESS_KEY_ID` and `AWS_SECRET_ACCESS_KEY`

So I naively changing the content of the `s3-yandex` secret and apply the corrected `ObjectStore`. But.... nothing happens.

I see the next in the logs of barman:

My expectations: that the backups would be streamed to a new bucket.

Commencez par les manifestes ScheduledBackup et ObjectStore de l’issue, puis comparez les valeurs appliquées de ObjectStore et du secret avec la commande d’archivage WAL de barman-cloud affichée dans les logs. Déterminez comment une destination ObjectStore et les identifiants sont actualisés, puis vérifiez que l’opération est terminée en observant que les archives WAL utilisent le nouveau bucket et les nouveaux identifiants.
