Description

We have a custom task in the repo that has an arcade equivalent:
https://github.com/dotnet/runtime/blob/main/src/tasks/WorkloadBuildTasks/GenerateFileFromTemplate.cs
https://github.com/dotnet/arcade/blob/main/src/Microsoft.DotNet.Build.Tasks.Templating/src/GenerateFileFromTemplate.cs

Here's a place where I did it: 095808b

We should be able to just add a PackageReference where that's needed to use the task and delete the copy in dotnet/runtime.
