feat: add rns registry contract address

[jonathansmirnoff]

PR Description

This PR adds the RNS Registry contract address for Rootstock Mainnet.

By including this address, Rootstock becomes compatible with ENS-related operations offered by the wagmi library. Since RNS is protocol-compatible with ENS, developers will now be able to use standard ENS methods (e.g., getEnsAddress, resolveName, etc.) when interacting with .rsk domains on Rootstock.

This is an important step toward improving interoperability and enhancing the developer experience across the Rootstock ecosystem.

The repository is archived because it is now in read-only mode—the protocol itself is fully deployed and actively used on the Rootstock blockchain. RNS protocol continues to be a foundational component of the Rootstock ecosystem.

📌 Where is RNS actively used?

Here are several examples that demonstrate the ongoing relevance and integration of the RNS protocol:

• 📘 Devportal Documentation
  Extensive technical documentation on RNS is available here:
  https://dev.rootstock.io/concepts/rif-suite/rns/

• 📦 RNS SDK
  The rsksmart/rns-sdk is widely used by dApps for domain resolution, registration, and management.

• 🔍 Blockchain Explorers
