Fix Redis service hostname after redis-bb subchart upgrade

General MR

Summary

Fix release cluster testing issue: tcp: lookup argocd-argocd-redis-bb-headless.argocd.svc.cluster.local on 10.100.0.10:53: no such host

• Corrects the Redis headless service hostname in ArgoCD configuration following the breaking change introduced in Redis subchart upgrade from 21.2.9-bb.0 to 22.0.4-bb.1
• Updates upstream.externalRedis.host from argocd-argocd-redis-bb-headless.argocd.svc.cluster.local to redis-bb-headless.argocd.svc.cluster.local

Problem

The Redis BigBang wrapper chart version 22.0.4-bb.1 introduced explicit name overrides (fullnameOverride: "redis-bb"), which changed the generated service name from argocd-argocd-redis-bb-headless to redis-bb-headless. The ArgoCD configuration was still pointing to the old service name, causing connection failures.

Changes

• chart/values.yaml: Updated upstream.externalRedis.host to use the correct service name
• chart/Chart.yaml: Bumped version to 8.3.4-bb.1

Testing

• Verified Redis service is accessible at the new hostname
• Confirmed ArgoCD can connect to Redis
• Tested upgrade path from previous version

Impact

This is a required fix for anyone using the BigBang ArgoCD package with the embedded Redis subchart. Without this change, ArgoCD cannot connect to its Redis backend.
