[sdk] KFPv2: Custom Container component set bool default value False to 0 which caused runtime failure

[zijianjoy]

Environment

• KFP version:
  KFP 2.0.0-alpha.4
• KFP SDK version:
  SDK 2.0.0-beta4

Steps to reproduce

Create the following custom container component:

from kfp.dsl import Input, Output, Artifact, container_component, ContainerSpec

@dsl.container_component
def create_dataset(experiment_name: str, experiment_namespace: str, experiment_timeout_minutes: int, 
                   experiment_spec_json: Input[Artifact], parameter_set: Output[Artifact], delete_finished_experiment: bool = False):

    return ContainerSpec(
        image='docker.io/kubeflowkatib/kubeflow-pipelines-launcher',
        command=['python', 'src/launch_experiment.py'],
        args=[
          '--experiment-name',           experiment_name,
          '--experiment-namespace',      experiment_namespace,
          '--experiment-spec',           experiment_spec_json.path,
          '--experiment-timeout-minutes',experiment_timeout_minutes,
          '--delete-after-done',         delete_finished_experiment,
          '--output-file',               parameter_set.path,
        ])

Note that delete_finished_experiment has a default value False.

When compiling the pipeline, this component is converted to IR with the following format:

    tasks:
      create-dataset:
        cachingOptions:
          enableCache: true
        componentRef:
          name: comp-create-dataset
        dependentTasks:
          - create-katib-experiment-task
        inputs:
          artifacts:
            experiment_spec_json:
              taskOutputArtifact:
                outputArtifactKey: experiment_spec_json
                producerTask: create-katib-experiment-task
          parameters:
            delete_finished_experiment:
              runtimeValue:
                constant: 0
            experiment_name:
              componentInputParameter: name
            experiment_namespace:
              componentInputParameter: namespace
            experiment_timeout_minutes:
              runtimeValue:
                constant: 60
        taskInfo:
          name: create-dataset

Note that delete_finished_experiment has a runtime value as 0.

Expected result

What should the type of boolean default value be? I am expecting the value to be either of followings: bool false, bool False or string False. I didn't expect the value to be number 0.
