flux: update lookup call endpoints

Package Merge Request

Package Changes

The latest flux updated changed the targeted version of HelmRelease from v2beta1 to v2beta2, and therefore these calls to lookup were causing deprecation warnings. Benign, but annoying:

helm upgrade -i bigbang chart/ -n bigbang --create-namespace -f ../overrides/enable-minio.yaml -f ../overrides/ib-credentials.yaml -f chart/ingress-certs.yaml
W1221 10:42:46.416683   41358 warnings.go:70] v2beta1 HelmRelease is deprecated, upgrade to v2beta2

W1221 10:42:47.209331   41358 warnings.go:70] v2beta1 HelmRelease is deprecated, upgrade to v2beta2

This change updates the targeted version so these warnings are gone.
