chore(eks): update failing snapshots (aws#30829)

update `framework-integ/test/aws-eks/test/integ.eks-helm-asset.ts` that might fail in some cases:

1. set `aws.region` for the helm charts to ensure successful helm deployment
2. make sure each helm charts assertion use different chart source to avoid conflict
3. update the snapshots
