Prop 18: Configure onboarding module for Gravity Bridge

This proposal if passed will configure the onboarding module for channel-0 (Gravity Bridge). The onboarding module makes IBC transfers into and out of the Althea L1 EVM easier by auto-wrapping tokens bridged in from Ethereum. This means the users tokens go directly from their EVM wallet on ETH to their EVM wallet in the Althea EVM without requiring another transaction signature. If this feature is not enabled users will have to send a second transaction on Althea L1 to complete the bridge in process.
