[AWS::SageMaker::App] - [BUG] - #/AppType: CodeEditor is not a valid enum value

### Name of the resource

AWS::SageMaker::App

### Resource Name

_No response_

### Issue Description

I noted that in the CloudFormation documentation, 'CodeEditor' is not a valid value for AppType: https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/aws-resource-sagemaker-app.html#cfn-sagemaker-app-apptype. However, when I look up existing apps for my domain with AWS CLI (configured with click-ops), it does return my app with AppType 'CodeEditor'.

```
{
"Apps": [
{
"DomainId": "d-u0oecosdfsf",
"SpaceName": "code-editor-mike",
"AppType": "CodeEditor",
"AppName": "default",
"Status": "InService",
"CreationTime": "2025-04-22T07:24:35.004000+12:00",
"ResourceSpec": {
"SageMakerImageArn": "arn:aws:sagemaker:us-east-1:885854791233:image/sagemaker-distribution-cpu",
"SageMakerImageVersionAlias": "2.4.1",
"InstanceType": "ml.t3.medium"
}
}
]
}
```

### Expected Behavior

I expect CodeEditor to be a valid enum value, and CDK to create the app.

### Observed Behavior

```
_ToolkitError: The stack named dev-sagemaker-ai-stack failed creation, it may need to be manually deleted from the AWS console: ROLLBACK_COMPLETE: Properties validation failed for resource SagemakerCodeEditorApp with message:
[#/AppType: CodeEditor is not a valid enum value]
```

### Test Cases

Deploy the following with CDK:

```
const domain: CfnDomain;
const userProfile: CfnUserProfile;

new CfnApp(this, 'SagemakerCodeEditorApp', {
appName: 'CodeEditor',
domainId: domain.attrDomainId,
userProfileName: userProfile.userProfileName,
appType: 'CodeEditor',
resourceSpec: {
instanceType: 'ml.t3.medium',
sageMakerImageArn: `arn:aws:sagemaker:us-east-1:885854791233:image/sagemaker-distribution-cpu`,
},
});
```

### Other Details

_No response_

Start by comparing the AWS::SageMaker::App documentation enum with the AWS CLI response and the CfnApp example in the issue. Confirm the expected CodeEditor value and use the supplied CDK deployment case to verify that the resource accepts it and completes successfully.
