Issue Description

It seems that Reqnroll v2.0.0 projects fail to build on MacOS ARM64 processor machines.

The error message is similar to this:

/Users/<user>/.nuget/packages/reqnroll.mstest/2.0.0/build/Reqnroll.MsTest.targets(34,5): error MSB4216: Could not run the "ReplaceTokenInFileTask" task because MSBuild could not create or connect to a task host with runtime "NET" and architecture "arm64".  Please ensure that (1) the requested runtime and/or architecture are available on the machine, and (2) that the required executable "MSBuild.exe" exists and can be run.

With Reqnroll 1.0.0 it works!

Steps to Reproduce

• Get a MacBook M1
• Clone Reqnroll Quickstart (https://github.com/reqnroll/Quickstart)
• Run: dotnet build

After some debugging, it seems that the problem is caused by the change: https://github.com/reqnroll/Reqnroll/commit/5e81d0d0afb69c4a32ce0bd3e7c6b0f6ccf85113

If I remove the TaskFactory="TaskHostFactory" setting from the <UsingTask> entries at https://github.com/reqnroll/Reqnroll/blob/main/Reqnroll.Tools.MsBuild.Generation/build/Reqnroll.Tools.MsBuild.Generation.tasks#L9, the build starts to work.

We have introduced these settings to avoid file locks in Visual Studio when we develop Reqnroll itself, so probably the fix could be to somehow set this to conditional and only use it when it is calling from VS.
