Prop 178: Add stAtom Metadata to Gravity Bridge

This proposal connects the stAtom token from Stride to the Gravity Bridge. If accepted, it would establish metadata for the IBC denom ibc/F885EEDD236C0706DBC15DBE2722D695111C74A75EA1B188AE4688ADE63C98A5. This metadata would then be usable to deploy an ERC20 representation on Ethereum for the stAtom token. Voters should verify that the ibc hash is on channel-138, 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/F885EEDD236C0706DBC15DBE2722D695111C74A75EA1B188AE4688ADE63C98A5. For more about Stride see https://stride.zone/
