feat: configure preview/staging builds like console (#84)

Add release-please to the mix and make the config for this deployment
match `console`:
https://github.com/storacha/console/blob/68d09b57832d621c34916f0c127ef5c6c9553cf0/.github/workflows/deploy-storacha.yml#L14

This is particularly needed because the current config updates the
staging project constantly and doesn't give us a stable base to stage
changes before they go to production.
