/lgtm
already, just minor comment below which I didn't fully grok

cc @pboyd can you also kindly check please?
the goal here is to make a quick test that a Catalog API responds if the Manifests are deployed, ref kubeflow/hub#1685

Should we just merge this with the model registry files or do you want to have it explicitly separate @tarilabs ?

I'd prefer to keep these separate GHA and scripts, if that is okay with you, as we'd like to showcase Catalog also independently of Registry. Further will help pin-point if either fails their check. Wdyt?

Looks good to me.

Fair warning though, we've tweaked a few things upstream and we'll need some changes to this test when we bring those changes back down. Namely, we fixed some of the redundant names and added an optional istio overlay.

probably because of https://github.com/kubeflow/manifests/blob/65245b29afe55d5d7b699fdf33903b32e21db9f5/applications/trainer/upstream/overlays/manager/kustomization.yaml#L18
