s3-operator flag provided but not defined: -s3-endpoint-url

Using the helm chart `inseefrlab\s3-operator` (v0.5) with value:

```
s3:
endpointUrl: minio.platform:9000
```

results in error on `s3-operator` pod (image: `inseefrlab/s3-operator:latest`):

```
flag provided but not defined: -s3-endpoint-url
```

Probable cause is that the parameter has been removed/renamed and since the image in the chart is not versioned it fails with newer manager.
