In VSCode hovering over a component tag should show the full component type name

[danroth27]

In VS if you hover over a component tag you get the full type name:

In VSCode you only get the type name without the namespace:

We should show the full type name of the component when hovering.

@danroth27 shouldn't this go to the razor repo? Let me know if that's not the case

This is because in VS we get Roslyn to provide the hover for components. The solution here is to move hover to "single server" in VS Code. No it's not!

The reason for this bug is that we have two different code paths for generating hovers, one that creates WPF text runs for Visual Studio, and one that creates markdown strings for all other LSP clients. By forcing the isVSClient variable to be false in the HoverInfoService, this can be made to repro in VS:
https://github.com/dotnet/razor/blob/main/src/Razor/src/Microsoft.AspNetCore.Razor.LanguageServer/Hover/HoverInfoService.cs#L227

So the fix here would for the code in DefaultLSPTagHelperTooltipFactory be updated to match the logic in DefaultVSLSPTagHelperTooltipFactory when producing hover content.
