cfn generate not creating models.

Typescript resource models are not being generated by cfn generate. A similar workflow using java generates the S3 and BucketPolicy models, but nothing with typescript.

Environment Details:
Windows 10 Pro
cfn 0.2.28
Python 3.10.10
Node v18.13.0

Same results with:
Mac OS 12.6.3
cfn 0.2.28
Python 3.9.16
Node v18.12.1

Hook spec:
```
{
"typeName": "MyCompany::Test::Hook",
"description": "Test",
"sourceUrl": "https://github.com/maclema/test",
"documentationUrl": "https://github.com/maclema/test/README.md",
"typeConfiguration": {
"properties": {},
"additionalProperties": false
},
"required": [],
"handlers": {
"preCreate": {
"targetNames": [
"AWS::S3::Bucket",
"AWS::S3::BucketPolicy"
],
"permissions": []
},
"preUpdate": {
"targetNames": [
"AWS::S3::Bucket",
"AWS::S3::BucketPolicy"
],
"permissions": []
},
"preDelete": {
"targetNames": [
"AWS::S3::Bucket",
"AWS::S3::BucketPolicy"
],
"permissions": []
}
},
"additionalProperties": false
}
```

cfn generate output:

```
Generated files for **MyCompany::Test::Hook**
```

Resulting models.ts file:

```
// This is a generated file. Modifications will be overwritten.
import { BaseModel, Dict, integer, Integer, Optional, transformValue } from '@amazon-web-services-cloudformation/cloudformation-cli-typescript-lib';
import { Exclude, Expose, Type, Transform } from 'class-transformer';

export class TypeConfigurationModel extends BaseModel {
['constructor']: typeof TypeConfigurationModel;

}
```
