fix(multichain-testing): update starship helm chart repo URL

[mujahidkay]

closes: #10862

Description

Cosmology has rebranded to Hyberweb which now leads https://cosmology-tech.github.io/starship to a 404. This PR updates the helm chart repo url for starship to unbreak dapp-orch-basics and agoric-sdk's CI (failing multichain-e2e run). The change is fairly recent - around 2 days ago - so they haven't gotten to update all their docs yet. I stumbled upon the correct URL intuitively - which means I can't provide some docs or issue as proof other than the fact that it works now.
Edit: updated here
