fix(website): gitops deployment was missing chainId

[mjlescano]

This PR fixes the gitops deployment page, by doing the actual fix first, and also fixing the types on the builder so this kind of error is less likely.

1. The website hook was initialising the simulated build without chainId, that's fixed here: https://github.com/usecannon/cannon/pull/1378/files#diff-1c16184636ccf287d09107e881baa71fba0cc29067ff908c276919cf5922d6b4R266
2. Now, when fetching deployment packages we make sure it includes chainId to be consistent with old deployments, kinda like a migration: https://github.com/usecannon/cannon/pull/1378/commits/9c6c542b628e755ae4ac5e7f1c89df834da64a64
