function Get-TemporaryDirectory {
    <#
    .SYNOPSIS
        Creates a new temporary directory with a random name.
    
    .DESCRIPTION
        The Get-TemporaryDirectory function generates a random directory name and creates a new directory in the specified parent directory (or the system's temporary directory if no parent directory is specified) with that name.
    
    .PARAMETER ParentDirectory
        The parent directory in which the temporary directory should be created. If not specified, the system's temporary directory will be used.
    
    .PARAMETER Prefix
        The prefix to use for the temporary directory name. If not specified, a random prefix will be generated.
    
    .PARAMETER Suffix
        The suffix to use for the temporary directory name. If not specified, a random suffix will be generated.
    
    .EXAMPLE
        PS C:\> Get-TemporaryDirectory -ParentDirectory "C:\Temp" -Prefix "mytemp" -Suffix "data"
        C:\Temp\mytemp_w3jv5q5w.5zv_data
    
        This example creates a new temporary directory with the name "mytemp_w3jv5q5w.5zv_data" in the "C:\Temp" directory and returns the path of the new directory.
