<#
.SYNOPSIS
Creates a new notebook in a specified Microsoft Fabric workspace.
 
.DESCRIPTION
This function sends a POST request to the Microsoft Fabric API to create a new notebook
in the specified workspace. It supports optional parameters for notebook description
and path definitions for the notebook content.
 
.PARAMETER WorkspaceId
The unique identifier of the workspace where the notebook will be created.
 
.PARAMETER NotebookName
The name of the notebook to be created.
 
.PARAMETER NotebookDescription
An optional description for the notebook.
 
.PARAMETER NotebookPathDefinition
An optional path to the notebook definition file (e.g., .ipynb file) to upload.
 
.PARAMETER NotebookPathPlatformDefinition
An optional path to the platform-specific definition (e.g., .platform file) to upload.
 
.EXAMPLE
 Add-FabricNotebook -WorkspaceId "workspace-12345" -NotebookName "New Notebook" -NotebookPathDefinition "C:\notebooks\example.ipynb"
 
 .NOTES
- Requires `$FabricConfig` global configuration, including `BaseUrl` and `FabricHeaders`.
- Calls `Test-TokenExpired` to ensure token validity before making the API request.
