Code Review

This pull request adds a new Python snippet create_data_profile_scan.py to demonstrate creating a Dataplex Data Profile Scan using global API endpoint routing. The review feedback points out that the CreateDataScanRequest requires a data_scan_id parameter, which is currently missing. It is recommended to add data_scan_id to the function signature, document it in the docstring, and pass it to the request payload.

This sample has been manually tested:

Also the data scan is visible on the GCP web ui:

To maintain consistency with the other sample created, this file should be renamed following that same pattern. create_data_profile_scan_global.py
