What are you seeing?

I am using %temp%/cake-build/addins in the config for the addins and tools.

When running this from powershell (A):

.\build.ps1 --target initialize --verbosity verbose --debug

The directory for the addins is C:/Users/DEVELO~1/AppData/Local/Temp/cake-build/addins

When running cake directly (B), the directory is C:/Users/developer/AppData/Local/Temp/cake-build/addins

The directories when searching for files in NuGet packages are:

A: ../../../../../../../developer/AppData/Local/Temp/cake-build/addins/Cake.FileHelpers.7.0.0/lib/net8.0/Cake.FileHelpers.dll
B: lib/net6.0/Cake.FileHelpers.dll

The first one clearly fails to figure out the (relative) directory of the NuGet package.

Will try to figure out what's causing this and create a PR.

What is expected?
