Context

In the test_starknet_ics20_contract test, once the Cosmos and Starknet chains are connected (via the handshake process), a dummy msg_recv_packet is created. To fully simulate the relaying of a packet from Cosmos to Starknet, the msg_recv_packet should be constructed based on a previously submitted MsgTransfer to the Cosmos chain.

Additionally, the packet should be acknowledged on the Cosmos chain and should cover two scenarios: first, when the incoming token into Starknet is an IBC-minted token, and second, when it is a native token previously sent to Cosmos and now being unescrowed.
