Description

Bumps the default Hubble Relay image in the retina-hubble chart from mcr.microsoft.com/oss/cilium/hubble-relay:v1.15.0 to mcr.microsoft.com/oss/cilium/hubble-relay:1.16.1. The newer image includes the upstream Hubble Relay TLS ALPN handling needed by recent Hubble CLI / grpc-go clients.

The default digest value is updated to the manifest-list digest for 1.16.1.

@officialasishkumar I've just checked and found out that the mirrored MCR images are deprecated, might be better to use the upstream quay.io/cilium/ images here (latest if possible). Also we might want to keep the relay and UI image aligned.

Updated the chart defaults to use the upstream quay.io/cilium relay, UI, and certgen images, and force-pushed the branch.

@officialasishkumar thanks, can you update the PR description with the actual image changes + tests done and screenshots to show that everything is working correctly?
