Add fully qualified name to cref ObservableObject in xml comments for files generated by ObservableObjectGenerator

[RobGess]

Describe the bug

When using the ObservableObject attribute from the CommunityToolkit.Mvvm v8.3.2 package on the code behind partial class of a WPF UserControl like this:

The reference <see cref = "ObservableObject"/> symbol reference is not resolved in the *.g.cs file generated by the ObservableObjectGenerator.

First, I opened a ticket in the DocFx project because I found this issue working with DocFx. Analyzing the problem with a contributor from the DocFx team, I was sent over here.

How to fix problem
ObservableObject should be referenced by using fully qualified name.
(e,g, <see cref = "global::CommunityToolkit.Mvvm.ComponentModel.ObservableObject"/>)

It probably can be fixed by changing following line.
https://github.com/CommunityToolkit/dotnet/blob/v8.3.2/src/CommunityToolkit.Mvvm/ComponentModel/ObservableObject.cs#L275

2. Add UserControl
3. Add [ObservableObject] attribute to partial class *.xaml.cs of the UserControl.
4. Check SourceGenerator's *.g.cs file's SetProperty method's comments.
