[v9.9][maui] MAUI/iOS/Android project templates missing when only .NET11 is installed globally

[mauroa]

Describe the issue

If I only have .NET 11 globally installed (with MAUI workloads) and I try to create a new project from VS Code, I won't see the MAUI/iOS/Android templates.

It seems C# DevKit is using a .NET 10 installation somewhere, which doesn't have MAUI workloads so it doesn't have anything to show.

Similar root cause as #3440, it might need to recognize the global .NET 11 installation somehow

Note: seems CSI can also reproduce this with a .NET 10 global installation somehow

Steps to reproduce

1. Ensure .NET 11 only is installed globally
2. Explorer: Create .NET project -> MAUI templates doesn't show up

Expected behavior

MAUI/Android/iOS template always exist in "Create a new .NET project" list
