axaml code completion not available when UseArtifactsOutput is used; incomplete otherwise

[just-ero]

Describe the bug

It appears that when using UseArtifactsOutput (new addition in .NET 8), Avalonia is incapable of finding the build artifacts, such that the Build the project pop-up appears even after building the project.

When not using UseArtifactsOutput, completion is still incomplete, only suggesting the closing tag for the root element (e.g. </Application>). This may be caused due to being on an Avalonia version above the suggested 11.0.2, but I'm not sure (the README only mentions that the previewer will not work).

To Reproduce

1. Create or open any Avalonia project in Visual Studio Code.
2. Clear (dotnet clean) or remove the bin/ and obj/ directories for the test project.
3. Create (dotnet new buildprops) or open a Directory.build.props file in the root of the workspace.
4. Add a <UseArtifactsOutput>true</UseArtifactsOutput> element.
5. Attempt to receive code completions in any axaml files.
