Since Zod v4 is now stable, it’s time to upgrade, to avoid dependency conflicts

Zod v3.20 is still listed as a dependency in package.json in this package.

@DenisBessa yes correct, but it's no longer a peer dependency which should prevent the conflict happened before. Once possible we will defiantly migrate to v4 🙏
