Inconsistent field names in helm_chart/HyperPodHelmChart/values.yaml

In the helm [values.yaml](https://github.com/aws/sagemaker-hyperpod-cli/blob/main/helm_chart/HyperPodHelmChart/values.yaml) file, there is this section:

```
trainingOperators:
enabled: true

inferenceOperators:
enabled: false
```

The field name "trainingOperators", "inferenceOperators" are inconsistent with actual sub-chart names.
It is being a pitfall for customers, because even if customers try to override parameters of sub-charts under "trainingOperators" and "inferenceOperators", it doesn't take effect, because of the mismatch.

Please see the [Chart.yaml](https://github.com/aws/sagemaker-hyperpod-cli/blob/main/helm_chart/HyperPodHelmChart/Chart.yaml) file as well.

Only training-operator and inference-operator are inconsistent.

```
- name: training-operators
version: "0.1.0"
repository: "file://charts/training-operators"
condition: trainingOperators.enabled
```

```
- name: hyperpod-inference-operator
version: "0.1.0"
repository: "file://charts/inference-operator"
condition: inferenceOperators.enabled
```

Please fix this inconsistency.
