fix:[doc] useSignTransaction example error

[klren0312]

Description

the useSignTransaction doc has a error.
In the code const { bytes, signature, reportTransactionEffects } = await signTransaction, signTransaction will return void, so need to use onSuccess to get these params.

signTransaction(
  {
    transaction: new Transaction(),
    chain: 'sui:devnet',
  },
  {
    onSuccess: async ({ bytes, signature, reportTransactionEffects }) => {
       // do something
    })
  }
)

Test plan

this code is true: https://github.com/MystenLabs/sui/blob/main/sdk/docs/examples/wallet-hooks.tsx#L241-L254
but the doc is error, it will confuse developers

I think there might be something else going on. Can you double check that you are using mutateAsync not mutate when you define signTransaction? The async version should resolve to a promise with the bytes and signature
