ROX-30141: Use snapshots instead of pipelineruns for getting built images

[kurlov]

We can no longer rely on pipelineruns CR to fetch image references. Snapshots are more reliable.
One caveat comparing Konflux UI is that snapshots contains images with digests and no tags, so I added "name" value as well to show which digest belongs to which OCP version.

OK example:

./scripts/get-built-images.sh 0980bc57029612d0c51484bff4dd00ff84d784eb master
