Post Actions are ignored when template is used by any IDE

### Product

dotnet CLI (dotnet new)

### Describe The Bug

I'm creating some templates to speed up the creation process for certain projects, specifically when using clean architecture. My templates work correctly when used from the terminal, but if I try to create any of these projects from any IDE, it ignores the postActions. I tried it with Rider and Visual Studio, and it didn't work with either. Basically, I'm adding dynamic NuGet packages depending on whether the user wants to use NativeAOT or not, but these are completely ignored.

Here is the code, as you can see I have to comment the post actions to go in other way.:
