Azure Key Vaults for secret or credential protection at Fabric Notebooks

Hi ibarrau,

Firstly, in your code samples you’re still using mssparkutils. Why not switch to notebookutils? It’s the newer approach, automatically available in Fabric notebooks without any extra imports, and it represents the future direction for notebook development. See the NotebookUtils documentation.

Secondly, when explaining how to set up Azure Key Vault and use it in Fabric, consider adding details about configuring a private endpoint between the workspace and the Key Vault. This step significantly improves security by ensuring traffic stays within the private network instead of going over the public internet.
