Error with hyperpod start-job command

Error when running hyperpod start-job command from [hyperpod fsdp workshop example](https://catalog.workshops.aws/sagemaker-hyperpod-eks/en-US/02-fsdp/03-train-with-hyperpod-cli):

```

2025-06-06 16:47:42 - hyperpod_cli.validators.job_validator - ERROR - Scheduler type is 'SageMaker' however cannot find namespace 'aws-hyperpod' managed by SageMaker. Please ensure namespace exists and you have 'get' access to it.
```

I've tried `default` and `kubeflow` namespaces as well. The only namespaces it works in are the namespaces created from making the Team Quota allocations in [Task Governance workshop example](https://catalog.workshops.aws/sagemaker-hyperpod-eks/en-US/10-task-governance/02-example/01-example-setup).
