[Bug]: Cannot read properties of undefined error when promise is called on a request

### Self-service

- [ ] I'd be willing to implement a fix

### Describe the bug

Cannot read properties of undefined error when promise is called on a request

### Steps to reproduce

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

const client = new AWS.S3({ region: "us-west-2" });
const request = client.listBuckets();
await request.promise();
```

### Observed behavior

```console
TypeError: Cannot read properties of undefined (reading 'length')
at removePromiseForCallExpression (/Users/trivikr/.npm/_npx/7c563efbb7515419/node_modules/aws-sdk-js-codemod/dist/transforms/v2-to-v3/apis/removePromiseForCallExpression.js:33:47)

```

### Expected behavior

```js
import { S3 } from "@aws-sdk/client-s3";

const client = new S3({ region: "us-west-2" });
const request = client.listBuckets();
await request;
```

### Environment

```shell
aws-sdk-js-codemod: 2.0.0
- jscodeshift: 0.16.0
- recast: 0.23.9
```

### Additional context

_No response_

Reproduce the issue with the S3 request example, then start at removePromiseForCallExpression in transforms/v2-to-v3/apis/removePromiseForCallExpression.js and trace its call from removePromiseCalls.js. The fix is complete when this input no longer raises the undefined length error and produces the expected await request conversion.
