[Feature]: The v2-to-v3 transform should convert to v3 style of making API calls

### Self-service

- [ ] I'd be willing to implement this feature

### Template name

v2-to-v3

### Input code

```js
import AWS from "aws-sdk";

const region = "us-west-2";
const client = new AWS.DynamoDB({ region });
const response = await client.listTables().promise();
```

### Expected Output

Existing output

```js
import { DynamoDB } from "@aws-sdk/client-dynamodb";

const region = "us-west-2";
const client = new DynamoDB({ region });
const response = await client.listTables();
```

Recommended output

```js
import { DynamoDB, ListTablesCommand } from "@aws-sdk/client-dynamodb";

const region = "us-west-2";
const client = new DynamoDB({ region });
const response = await client.send(new ListTablesCommand({}));
```

### Additional context

Reference blog post: https://www.10printiamcool.com/updating-to-nodejs-18-and-aws-javascript-sdk-v3-part-1

Start with the v2-to-v3 transform entry point and its existing fixtures or tests, then trace how the input API call is converted to v3 code. Update the transformation so the expected output imports the operation command and sends a new command instance; add or adjust coverage for the provided DynamoDB listTables example.
