conda-env-kernel-image example is broken

After following the steps listed [here](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/conda-env-kernel-image) exactly I began a SageMaker Studio session. After creating selecting the custom image and beginning a console I received the following error:
```
Invalid response: 404 Not Found
Kernel with name [myenv] does not exist in image [arn:aws:sagemaker:REGION:ACCOUNT_ID:image/conda-test-kernel] on the KernelGateway App [conda-test-kernel-ml-t3-medium-HASH]. To make the kernel available, either update your AppImageConfig to have same kernel name as available in the image or update your SageMaker Image to have the kernel with the same name as specified in AppImageConfig. You can use https://github.com/aws-samples/sagemaker-studio-custom-image-samples/blob/main/DEVELOPMENT.md#local-testing for testing your image locally.
```

The `Dockerfile` and `environment.yml` are identical to the example. Here is the `app-image-config-input.json` file:
```json
{
"AppImageConfigName": "myenv-config",
"KernelGatewayImageConfig": {
"KernelSpecs": [
{
"Name": "myenv",
"DisplayName": "Python [conda env: myenv]"
}
],
"FileSystemConfig": {
"MountPath": "/home/sagemaker-user",
"DefaultUid": 0,
"DefaultGid": 0
}
}
}
```

And here is the anonymized `create-domain-input.json` contents:
```json
{
"DomainId": "d-xxxxxxxxx",
"DefaultUserSettings": {
"ExecutionRole": "ROLE_ARN",
"KernelGatewayAppSettings": {
"CustomImages": [
{
"ImageName": "conda-test-kernel",
"AppImageConfigName": "myenv-config"
}
]
}
}
}
```
I used `IMAGE_NAME=conda-test-kernel` throughout. Other things to note:
* `aws sagemaker describe-image-version` shows `"ImageVersionStatus": "CREATED"`
* `aws sagemaker describe-app-image-config` gives back all the expected information

I **believe** the issue is that `conda` doesn't automatically follow the kernelspec. This quirk **needs** to be covered in the README for this example. Unfortunately I haven't figure out the solution yet. Any help is appreciated.
