[Tracking] Update 08-wasm client when it is merged into main

[aeryz]

08-wasm client is still being developed under feat/wasm-clients branch of ibc-go and it's still changing frequently. This issue will track the issues/PR's and note the changes so that we don't have hard time when we update.

Here are the PRs/issues that propose changes in the public API, or have notable changes that are good to know:

1. Return error before trying to initialize the contract by storing the code hash: Only store code hashes in store. cosmos/ibc-go#4292

Changes that are already been implemented:

1. CodeId field in the ClientState is changed to CodeHash.
2. Code field in MsgStoreCode is changed to WasmByteCode
3. As this spec change says: ICS8: Update the WASM Client spec cosmos/ibc#901, the read-only calls are changed to be queries, and write calls are changed to sudo calls.
