fix(multichain-testing): update starship helm chart repo URL (#10863)

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](https://github.com/Agoric/agoric-sdk/actions/runs/12867100606/job/35871037526#step:9:500)). 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](https://github.com/hyperweb-io/telescope/blob/f2746ee9a2fae655a7dfbb65cc6695067cb6db39/packages/starship/scripts/install.sh#L24)
