[browser] Publish `wasmbrowser` app from Visual Studio doesn't respect "include RID in output path"

[maraf]

1. Install WebAssembly Browser App template via command: dotnet workload install wasm-experimental
2. Create a new WebAssembly Browser App via Visual studio.
3. Publish the project to folder.

Output is located in bin/Release/net8.0/publish instead of bin/Release/net8.0/browser-wasm/publish

The same setup works for blazorwasm template

It is a different issue, because it uses completely different SDK under the hood (the plan is to migrate to the SDK used by wasmbrowser)

[maraf]

The issue is this workaround

runtime/src/mono/nuget/Microsoft.NET.Sdk.WebAssembly.Pack/build/Microsoft.NET.Sdk.WebAssembly.Browser.targets

Lines 198 to 199 in 43b55fa

	<!-- Workaround for https://github.com/dotnet/sdk/issues/12114-->
	<PublishDir Condition="'$(AppendRuntimeIdentifierToOutputPath)' != 'true' AND '$(PublishDir)' == '$(OutputPath)$(RuntimeIdentifier)\$(PublishDirName)\'">$(OutputPath)$(PublishDirName)\</PublishDir>

I'm not sure yet why I see it working for Blazor SDK correctly (maybe I oversaw it doesn't?)

The FolderPublish.pubxml is different

WasmBrowser

<?xml version="1.0" encoding="utf-8"?>

Which might be related to project capabilities

In recent testing it seems that publish from VS dialog doesn't do publish at all. I'm seeing running a Build target.
