[Content Improvement] Insufficient Lake Formation permission when creating Feature Store

**Link to the notebook**
https://github.com/aws/amazon-sagemaker-examples/blob/master/end_to_end/1-data-prep-e2e.ipynb

**What aspects of the notebook can be improved?**
For AWS users who have already enabled Lake Formation as new data lake permission model, when creating Feature Store, it will throw "Access denied" error shown as below:

`'FeatureGroupStatus': 'CreateFailed',
'FailureReason': 'Insufficient Lake Formation permission(s): Required Create Database on Catalog (Service: AWSGlue; Status Code: 400; Error Code: AccessDeniedException; Request ID: 2e3e108b-54f0-49d4-86fb-4a566cf4xxxx; Proxy: null)',`

One can reproduce this issue when enable Lake Formation as default permissions for newly created databases and tables, and then run this notebook.

**What are your suggestions?**
Add the SageMaker execution role as Lake Formation as database creator will solve this problem.
