Bug Description

When I run MakePQX verify test.pqx it fails with this exception:

System.IO.FileLoadException: Could not load file or assembly 'System.Threading.Tasks.Extensions, Version=4.2.0.1, Culture=neutral, PublicKeyToken=cc7b13ffcd2ddd51' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)

Additional Context

I downloaded version 2.145.5 of the Microsoft.PowerQuery.SdkTools nuget package and used that version of MakePQX and it worked without throwing an exception. I haven't tried every version between 2.145.5 and 2.153.3, but I know for sure that 2.150.3 and 2.153.3 have this same issue.

I can repro and confirmed that the issue still exists in the latest release - 2.154.1.
