# This script is only for AKS cluster testing. It reads the template files (Chart-template.yaml and values-template.yaml),
# replaces placeholders with actual values, removes specific sections, 
# and then writes the modified content back to new files (Chart.yaml and values.yaml).
# The placeholders replaced include HELM_CHART_NAME, IMAGE_TAG, MCR_REPOSITORY, ARC_EXTENSION, 
# AKS_REGION, and AKS_RESOURCE_ID. It also removes the dependencies section from the 
# Chart-template.yaml file.
