chore: Remove ios simulator runway bucket link

[Cal-L]

Description

We are hiding the iOS simulator Runway bucket link for now since the bucket doesn't expose additional artifact files. That is where the zipped .app files live. We've reached out to the Runway team requesting this feature here - https://consensys.slack.com/archives/C06J3Q52MMY/p1745453655180929?thread_ts=1744297584.706479&cid=C06J3Q52MMY. As a follow up, we are exploring hosting a GH page to track prebuilds in the meantime - https://github.com/MetaMask/metamask-mobile-prebuilds
