Add YNX Testnet (eip155:6423) to WalletConnect Explorer

[JiahaoAlbus]

Adding a new chain to the Explorer

1. JSON-RPC spec for Wallets — YNX Testnet is fully EVM-compatible, so the existing Ethereum JSON-RPC spec applies.
   GitHub Link: https://github.com/ethereum-lists/chains/blob/master/_data/chains/eip155-6423.json

2. CASA namespace spec — EIP-155 namespace already exists for EVM chains.
   GitHub Link: https://github.com/ChainAgnostic/namespaces/tree/main/eip155

3. namespaces: eip155

4. chains:

   • eip155:6423 — testnet

5. RPC endpoint:

   • https://evm.ynxweb4.com

6. SLIP-0044 coin type: 60

YNX Testnet is the public test network for the YNX Chain ecosystem.

I understand that registering a chain with WalletConnect Explorer is for discovery and does not itself guarantee wallet or dapp support for the chain.
