SageMakerExecPolicy CREATE_FAILED - "Cannot exceed quota for PolicySize: 6144" when launching "Data Science Studio User Profile" in ap-southeast-1 region

When I tried to run the workshop in **ap-southeast-1** region, I failed to create SageMaker Studio Domain users when following [Create SageMaker Studio Domain users for a data science environment](https://catalog.us-east-1.prod.workshops.aws/workshops/c882cd42-8ec8-4112-9469-9fab33471e85/en-US/security-for-sysops/team-resources/secure-environment-lab#create-sagemaker-studio-domain-users-for-a-data-science-environment). When I drill the underlying CloudFormation Stack, I found **CREATE_FAILED - "Cannot exceed quota for PolicySize: 6144"** for resource **SageMakerExecPolicy**. By shortening the TeamName to single character (eg. t), the issue can be solved. It is proven that using the region with more characters (eg. **ap-southeast-1**) would trigger this issue.
