Fix 6c_r_iris registry pipeline by using local iris dataset input

[Chakradhar886]

Summary

• replace external iris dataset URL in the 6c_r_iris pipeline sample with a repo-local iris CSV
• remove runtime dependency on azuremlexamples.blob.core.windows.net for this workflow path

Root cause

The workflow started failing with ScriptExecution.StreamAccess.ConnectionFailure due to DNS resolution failure for azuremlexamples.blob.core.windows.net, while sample/workflow code remained unchanged.

Changes

• updated cli/jobs/pipelines-with-components/basics/6c_r_iris/pipeline.yml input path:
  • from: https://azuremlexamples.blob.core.windows.net/datasets/iris.csv
  • to: ../../../../assets/data/example-data/iris.csv

Validation

• confirmed new path exists from sample working directory
• scoped to a single file and single input path change

Notes

This is a targeted hotfix for the 6c_r_iris registry pipeline regression. A broader follow-up can migrate remaining samples away from the retired external sample host.
