chore(Error): add error wrapper for wallet rpc error code

[stanleyyconsensys]

This PR is to add an error wrapper to integrate the error code from 'get-starknet' wallet rpc error

To avoid breaking any existing error format/type
we extends the current snap error and create a error wrapper walletRpcError by using the data field from the SnapError Constructor

Example of an error object return to the Snap Consumer

{
    "code": 4001,
    "message": "User rejected the request.",
    "data": {
// Error wrapper
        "walletRpcError": {
// 'get-starknet' wallet rpc error code
            "code": 113
        }
    }
}

for now we have implement above format into

• UserRejectedOpError // Error that extends UserRejectedRequestError
• InvalidRequestParamsError // Error that extends InvalidParamsError
• UnknownError // Error that extends SnapError
• InvalidNetworkError // when network switch to a unknown error

END_COMMIT_OVERRIDE
