Create-Lang-Package-Variables-TS-Function.ps1

<# @gwblok 2020.04.15
Updates the CM Task Squence "Module" that maps Language Pack Packages that get downloaded and applied during IPU.
Requires that Language Packs were created with specific information
When you run, you set the "Build" to the OS Release ID that you used when creating the packages, I'm using 20H2 in this script currently, you'll want to update that ($ReleaseID)
Requires that you have a TS already named "Module - Download Language Pack 20H2"
Requires that the TS has a Step Called "Set Language Variables"

If you download my WaaS TS Pack, it will be included
