[Feature]: aws-sdk not changed after converted

### Self-service

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

### Describe the bug

I'd like to update my nodejs version from 16.x to 18.x.
And when I run `npx aws-sdk-js-codemod -t v2-to-v3`, he statement `var AWS = require("aws-sdk"); ` not changed after converted.

### Steps to reproduce

source fie
```javascript
var AWS = require("aws-sdk");
var endpoint = new AWS.Endpoint(domain);
var request = new AWS.HttpRequest(endpoint, region);

request.method = method;
request.path += index;
request.body = "";
request.headers["host"] = domain;
request.headers["Content-Type"] = "application/json";
request.headers["Content-Length"] = Buffer.byteLength(request.body);

var credentials = new AWS.EnvironmentCredentials("AWS");
var signer = new AWS.Signers.V4(request, "es");
signer.addAuthorization(credentials, new Date());

var client = new AWS.HttpClient();
client.handleRequest(
request,
null,
function (response) {
console.log(response.statusCode + " " + response.statusMessage);
var responseBody = "";
response.on("data", function (chunk) {
responseBody += chunk;
});
response.on("end", function (chunk) {
success(responseBody);
});
},
function (error) {
console.log("Error: " + error);
}
);
```

output
```javascript
var AWS = require("aws-sdk");

const { fromEnv } = require("@aws-sdk/credential-providers");

var endpoint = new AWS.Endpoint(domain);
var request = new AWS.HttpRequest(endpoint, region);

request.method = method;
request.path += index;
request.body = "";
request.headers["host"] = domain;
request.headers["Content-Type"] = "application/json";
request.headers["Content-Length"] = Buffer.byteLength(request.body);

var credentials = // JS SDK v3 switched credential providers from classes to functions.
// This is the closest approximation from codemod of what your application needs.
// Reference: https://www.npmjs.com/package/@aws-sdk/credential-providers
fromEnv("AWS");
var signer = new AWS.Signers.V4(request, "es");
signer.addAuthorization(credentials, new Date());

var client = new AWS.HttpClient();
client.handleRequest(
request,
null,
function (response) {
console.log(response.statusCode + " " + response.statusMessage);
var responseBody = "";
response.on("data", function (chunk) {
responseBody += chunk;
});
response.on("end", function (chunk) {
success(responseBody);
});
},
function (error) {
console.log("Error: " + error);
}
);

```

### Observed behavior

```console
$ npx aws-sdk-js-codemod -t v2-to-v3 part.js

### Expected behavior

require("aws-sdk"); should changed to something from '@aws-sdk/XXX' right?
And `AWS.Signers` ,`AWS.HttpRequest` , `AWS.Endpoint` should changed relevantly

### Environment

```shell
npx aws-sdk-js-codemod --version
aws-sdk-js-codemod: 1.0.0
- jscodeshift: 0.15.0
- recast: 0.23.4
```

### Additional context

_No response_

Reproduce the issue with the supplied part.js example by running the npx aws-sdk-js-codemod -t v2-to-v3 command. Start at the v2-to-v3 transform entry point and compare handling of require("aws-sdk"), AWS.Signers, AWS.HttpRequest, and AWS.Endpoint; done means the relevant APIs are converted consistently and the reported example no longer leaves the AWS v2 usage unchanged.
