PIPE-1091: Improve Pipeline Init Command - Add Arguments.Parameters and Remove metadata.generateName

[Copilot]

This PR improves the clarifai pipeline init command by updating the Argo workflow template generation to include input arguments and remove unnecessary metadata fields.

Problem

The pipeline init command was generating Argo workflow specifications that:

1. Lacked input arguments for pipeline steps, making it harder to pass parameters between steps
2. Included metadata.generateName which is not needed in the base template

Solution

Updated the get_pipeline_config_template() function in clarifai/cli/templates/pipeline_templates.py to:

Add Arguments.Parameters to Steps

Each pipeline step now includes structured input arguments:

templateRef:
  name: users/test-user/apps/test-app/pipeline_steps/stepA
  template: users/test-user/apps/test-app/pipeline_steps/stepA
arguments:
  parameters:
    - name: input_text
      value: "Input Text Here"

Remove metadata.generateName

The Argo workflow spec no longer includes the generateName field:

Before:

metadata:
  generateName: pipeline-name-
spec:
  entrypoint: sequence

After:

spec:
  entrypoint: sequence

Benefits

• Better Parameter Handling: Pipeline steps now have a clear structure for receiving input parameters
• Cleaner Templates: Removed unnecessary metadata field that cluttered the base template
• Improved Developer Experience: Users can immediately see how to pass arguments to their pipeline steps

Testing

• Validated template generation with 1, 2, and 3 step scenarios
• Confirmed both requirements are met in generated YAML output
• Security analysis completed with 0 alerts
• No impact on existing functionality - changes are isolated to template generation

<issue_description>Improve clarifai pipeline init command:

1. Add input arguments for the steps in argo workflow spec in config.yaml for pipeline
   e.g.

          templateRef:
            name: ...
            template: ...
          arguments:
                parameters:
                  - name: input_text
                    value: "Input Text Here"

2. Remove metadata.generateName in YAML string in pipeline.orchestration_spec.argo_orchestration_spec</issue_description>
