exec /opt/.sagemakerinternal/conda/kgw_variant: exec format error

I've been trying to use my own custom image in SageMaker Studio and I always get the same error when trying to associate a notebook to the kernel (as seen in SageMaker Studio) :

```
Failed to start kernel
Failed to launch app [xxxxxxx-ml-t3-medium-176855f5e1df73edeeb33d0c81f0]. InternalFailure
```

And, the only log event seen in CloudWatch for the image is:

`exec /opt/.sagemakerinternal/conda/kgw_variant: exec format error.`

At first I thought it might be a bug in my container, so I have carefully checked all the steps described in [DEVELOPMENT.md](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/blob/main/DEVELOPMENT.md).

And finally, to try to discard a bug in the platform I tried to use the examples
[echo-kernel-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/echo-kernel-image) and [python-poetry-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/python-poetry-image) without modifications from the repository and in both of them **the same error occurred**.

I have also tried the [tf23-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/tf23-image) example, and it works, so I have been comparing the images and my feeling is that it could be related to the base image (the operating system used in the container): [echo-kernel-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/echo-kernel-image) and [python-poetry-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/python-poetry-image) are based on `debian` and [tf23-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/tf23-image) is based on `ubuntu`. Could that be the issue?

Could you please confirm that [echo-kernel-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/echo-kernel-image) and [python-poetry-image](https://github.com/aws-samples/sagemaker-studio-custom-image-samples/tree/main/examples/python-poetry-image) images are working (as is) in current SageMaker Studio version?
