Prop 233: Add Althea L1 Metadata to Gravity Bridge

This proposal connects the Althea token from Althea L1 to the Gravity Bridge. If accepted, it would establish metadata for the IBC denom ibc/5B7B34C07642FAEAC81C04C488D5D622D7900600A9B37426EB0FA0B4D30AA9CE. This metadata would then be usable to deploy an ERC20 representation on Ethereum for the Althea token. Voters should verify that the ibc hash is on channel-168, that this channel matches the forwarding proposal submitted at the same time, and that the denom trace is for the correct token. This can be done using gravity query ibc-transfer denom-trace ibc/5B7B34C07642FAEAC81C04C488D5D622D7900600A9B37426EB0FA0B4D30AA9CE.
