Add main Native (STX) Token

I know this is a testnet and it will improves on, but I think it would be better if the native tokens (STX) were bridge first. Alltho the bridging experience was super smooth and I didn’t got any lag or any kind of problem in may testnet period, didn’t found any bugs butjust I’ll say that add more tokens and specially the native STX and Sepolia Testnet (ETH).
