Full support for notebookutils.credentials.getToken() when using a Service Principal

[frithjof_v]

When running a Notebook in the security context of a Service Principal, unfortunately notebookutils.credentials.getToken('pbi') and notebookutils.credentials.getToken('https://api.fabric.microsoft.com') only return a few scopes:

* Dataset.ReadWrite.All

* Lakehouse.ReadWrite.All

* MLExperiment.ReadWrite.All

* MLModel.ReadWrite.All

* Notebook.ReadWrite.All

* SparkJobDefinition.ReadWrite.All

* Workspace.ReadWrite.All

This severely limits the usability of the token when working in Fabric for other item types and Fabric REST APIs. Please make it so that the token can access all item types and all Fabric REST APIs.

The Service Principal has Contributor access to the workspaces and the Notebook is executed in the security context of the Service Principal.
