`DynamicTextTransformation` fails since `GenerationEnvironment` property is now public

[gitfool]

FWIW, I just tried using this tool with Visual Studio 2022 (17.9.0 Preview 5.0) and it failed with the following error:

Error		Running transformation: System.NullReferenceException: Object reference not set to an instance of an object.

But I then managed to get it to work by changing TypeLitePlus.T4/Scripts/Manager.ttinclude#L464 from:

_generationEnvironment = type.GetProperty("GenerationEnvironment", BindingFlags.Instance | BindingFlags.NonPublic);

to:

_generationEnvironment = type.GetProperty("GenerationEnvironment");
