There is a bug in RegisterModel implementation
The RegisterModel step is implemented in the SDK as two steps, a _RepackModelStep and a _RegisterModelStep.
The _RepackModelStep runs a SKLearn training step in order to repack the model.tar.gz to include any custom inference code in the archive.
The _RegisterModelStep then registers the repacked model.
The problem is that the _RepackModelStep does not propagate VPC configuration from the Estimator object:
https://github.com/aws/sagemaker-python-sdk/blob/cdb633b3ab02398c3b77f5ecd2c03cdf41049c78/src/sagemaker/workflow/_utils.py#L88
This cause the AccessDenied exception because repacker cannot access S3 bucket (all access which is not via VPC endpoint is bloked by the bucket policy)
The issue is opened against SageMaker python SDK: https://github.com/aws/sagemaker-python-sdk/issues/2302
