🐛 Show correct latest release per ClusterStack

We have shown always the same ClusterStackRelease as latest release,
even if it was a ClusterStack that does not own the ClusterStackRelease.

This was because we have in theory correctly searched for the latest
release, but then have not taken it due to a mistake with the wrong
index of a for loop
