What steps did you take and what happened:
create infrastructure Provider ex; CAPA with setting the container manager args to include a namespace

apiVersion: operator.cluster.x-k8s.io/v1alpha2
kind: InfrastructureProvider
metadata:
  name: aws
  namespace: capa-system
spec:
  configSecret:
    name: capa-manager-bootstrap-credentials
    namespace: capa-system
  deployment:
    containers:
      - command:
          - /manager
        args:
          "--namespace": "capa-system"
        name: manager
  version: v2.6.1

What did you expect to happen:
Expect to have the capa provider deployment args assigned with "--namespace"

Anything else you would like to add:
Found the check for the provider args here ignoring the namespace as argument.
