chore: add new channel details between chains cosmoshub and sentinel

[ironman0x7b2]

The Sentinel team has created a new channel between Cosmos Hub and Sentinel for IBC ERC-20 token transfers. Relayers will be running on both channel pairs.

This would be the first instance of a mainnet ibc connection registering an IBC channel with transfer on both ports. I believe some earlier assumptions were that there would only every be one trasnfer/transfer IBC channel per chain pair. Why not use the existing transfer/transfer IBC channel?

@JeremyParish69 An initial version of the IBC ERC20 smart contract exists for current channels, but it has fixed metadata and doesn’t allow assigning a new contract. To address this, we deployed a new contract with customized metadata and an IMintableAndBurnable implementation. This required setting up a new channel between Sentinel and Cosmos Hub.

Ok thanks for explaining, I think I understand. I'm trying to double check with the Skip team, and also need to figure out how we're going to play this at the Registry since it's a first occurrence that was never supposed to be allowed.

Btw, after talking with Skip, I believe this addition to be valid. This PR hasn't been forgotten--just working out the final details on how to handle it, but should be resolve soon, I believe.
