Docs: Feedback for Deploy Redpanda for Production in Kubernetes

[josemrs]

Issue description

I think the web is outdated. I wanted to deploy with Cluster scope, so I deployed the Operator's helm with no additionalCmdFlags as specified in the doc, however, it was deployed with --namespace=redpanda argument.

I finally found a test file with the info I needed https://github.com/redpanda-data/redpanda-operator/blob/v25.1.3/operator/chart/ci/02-cluster-values.yaml

The helm chart REDAME file is correct in git hub too, so it's only the web.

The web should say:

3. Deploy the Redpanda Operator in your chosen scope:
   a. To deploy in cluster scope, use:

helm repo add redpanda https://charts.redpanda.com
helm repo update
helm upgrade --install redpanda-controller redpanda/operator \
  --namespace <namespace> \
  --create-namespace \
  --version v25.3.1 \
  --set crds.enabled=true
  --set scope=Cluster
  --set webhook.enabled=true

Thanks.
