<#
.SYNOPSIS
   Retrieves the refresh history of a specified dataset in a PowerBI workspace.
 
.DESCRIPTION
   The Get-FabricDatasetRefreshes function uses the PowerBI cmdlets to retrieve the refresh history of a specified dataset in a workspace. It uses the dataset ID and workspace ID to get the dataset and checks if it is refreshable. If it is, the function retrieves the refresh history.
 
.PARAMETER DatasetID
   The ID of the dataset. This is a mandatory parameter.
 
.PARAMETER workspaceId
   The ID of the workspace. This is a mandatory parameter.
 
.EXAMPLE
   Get-FabricDatasetRefreshes -DatasetID "12345678-90ab-cdef-1234-567890abcdef" -workspaceId "abcdef12-3456-7890-abcd-ef1234567890"
 
   This command retrieves the refresh history of the specified dataset in the specified workspace.
 
.INPUTS
   String. You can pipe two strings that contain the dataset ID and workspace ID to Get-FabricDatasetRefreshes.
 
.OUTPUTS
   Object. Get-FabricDatasetRefreshes returns an object that contains the refresh history.
