369098: Fix Ingress Configuration for Bold BI Deployment

[Priyasunil26]

Fixes and Enhancements:

Resolved NGINX Ingress Configuration Issue:

1. Updated Ingress Rules for Bold ETL Service: Corrected the issue where /boldetl(/|$)(.*) was causing errors due to pathtype: prefix conflict. Implemented a solution to ensure proper routing and handling of paths.
   
   
2. Updated NGINX Ingress Configuration for Kubernetes: Addressed the deprecation warning related to kubernetes.io/ingress.class by removing kubernetes.io/ingress.class in annotation and adding it to spec.
   
   All changes have been tested locally and verified to resolve the reported issues without introducing new warnings or errors.
