AIB ConfigureOfficeApps.ps1 Script has a $templateFilePathFolder variable not called

Hey Team -- in the `ConfigureOfficeApps.ps1` script used to install Project and Visio, on line 303, this variable: $templateFilePathFolder, is not called so it returns a null value. This is an example attempting to run that script manually. I think that portion of the `#Cleanup` section can be taken out.

Open CustomImageTemplateScripts/CustomImageTemplateScripts_2023-09-15/ConfigureOfficeApps.ps1 and inspect line 303 in the #Cleanup section. Check how $templateFilePathFolder is used, then verify the cleanup behavior by running the script manually. Done means the unused variable reference is removed and the script no longer returns a null value there.
