GDK Build With Out Install (BWOI) does not grab dlls without undocumented manual setup

This issue I think stems from the fact that the gdk packages expect dll's to be copied over from an installed gdk file path to the unity projects Assets/Plugins folder.
Steps to reproduce:

1. Remove any locally installed GDK
2. Open the GDK Package sign in samples project and delete the plugins folder if anything exists there
3. Close the unity editor
4. Set up an extracted GDK directory suitable for BWOI
5. Set up your windows sandbox and login to a developer account
6. Add this build script to the project [Internal link]
7. Set any relevant BWOI env vars by opening a admin command terminal and setting the variables listed here https://docs.unity3d.com/Packages/com.unity.microsoft.gdk.tools@1.5/manual/build-without-install.html
8. From that same terminal run this command
   1. "EditorPath\Unity.exe" -batchmode -projectPath "ProjectPath" -logFile "EditorBWOI.log" -accept-apiupdate -buildTarget Win64 -executeMethod Build.WindowsMono -quit
9. Open the resulting build

Actual results: Sign in sample show errors related to missing dll's, look at attached log [Internal link]

Expected results: Sign in sample should work as expected

Reproducible with versions: 1.5.1

Tested on (OS): Win11
