Update sui.ts examples to reflect "@mysten/sui" 1.0 changes

[sagorahmed]

Description:

As part of the 1.0 release, the @mysten/sui.js package has been migrated to @mysten/sui.
Also, the TransactionBlock class has been renamed to Transaction and suiClient.signAndExecuteTransactionBlock renamed to suiClient.signAndExecuteTransaction
Here is the source of the migrated version: https://sdk.mystenlabs.com/typescript/migrations/sui-1.0

However, many dwallet examples still use the old imports:

dwallet-js-examples/src/sui.ts

Line 20 in 7c92147

import { SuiClient } from '@mysten/sui.js/client'

dwallet-js-examples/src/sui.ts

Line 21 in 7c92147

import { TransactionBlock as TransactionBlockSUI } from '@mysten/sui.js/transactions'

These should now be updated to:

import { SuiClient } from '@mysten/sui/client';
import { Transaction as TransactionBlockSUI } from '@mysten/sui/transactions';

Some of the classes need to be updated also:

dwallet-js-examples/src/sui.ts

Line 131 in 7c92147

const createCapInSuiRes = await suiClient.signAndExecuteTransactionBlock({

dwallet-js-examples/src/sui.ts

Line 191 in 7c92147

let approveMsgRes = await suiClient.signAndExecuteTransactionBlock({

To this latest class:
suiClient.signAndExecuteTransactionBlock ----->>>>> suiClient.signAndExecuteTransaction

Update official documentation and code samples to reflect the new package name and renamed classes.
