[feature] Update pytorch launcher component

[anishasthana]

Feature Area

What feature would you like to see?

The pytorch launcher component hasn't been updated in a while. We should update the component to work with Pipelines v2 concepts and be better aligned with the latest version of the Kubeflow Training operator.

Related: kubeflow/training-operator#2068

What is the use case or pain point?

It will make it easier for new community members to use the Training Operator with Pipelines

Is there a workaround currently?

Manually written custom code.
