[dotnet] If, when creating a project, dotnet is not installed on the system, the extension goes into eternal loading.

Describe the bug

Hello everyone!
The other day I reinstalled the system and after installing vscode, I simply installed the vscode-avalonia extension. I expected that the extension would first install the dotnet I needed through another extension vscode-dotnet-runtime, but this did not happen.

To Reproduce

Prerequisites:

1. There are no installed dotnet on system.
2. Fresh installation of vscode without any extensions.
3. Only installed vscode-avalonia extension.

Steps to reproduce:

1. Open folders
2. Click Create Avalonia Project
3. Select avalonia.mvvm project
4. Select folder to place project files
