Microsoft.Extensions.FileProviders.Embedded Fails in .NET 10 with InvalidOperationException

### Is there an existing issue for this?

### Describe the bug

When migrating a project that uses Microsoft.Extensions.FileProviders.Embedded from .NET 8 to .NET 10, the application fails at runtime with a System.InvalidOperationException. The build process also generates a warning suggesting the package may no longer be necessary.

This functionality worked correctly in .NET 8 but is broken after upgrading to the .NET 10 RC.

### Expected Behavior

The application should start and serve the files embedded from the wwwroot directory, just as it did in .NET 8.

### Steps To Reproduce

Create a new ASP.NET Core Web Application targeting .NET 10.

Modify the .csproj file to include the following settings to embed the wwwroot folder:

```xml

net10.0
enable
enable
true

```

Use the following code in Program.cs to serve the embedded files:

```csharp
var builder = WebApplication.CreateBuilder(args);
var app = builder.Build();

app.UseFileServer(new FileServerOptions
{
RequestPath = "",
FileProvider = new Microsoft.Extensions.FileProviders.ManifestEmbeddedFileProvider(
typeof(Program).Assembly, "wwwroot"
)
});

app.Run();
```

The application fails to start with the following runtime exception:

```text
System.InvalidOperationException: “Could not load the embedded file manifest 'Microsoft.Extensions.FileProviders.Embedded.Manifest.xml' for assembly 'NetProbe'.”
```

A build warning is displayed:

```text
PackageReference 'Microsoft.Extensions.FileProviders.Embedded' will not be removed. Consider removing this package from your dependencies as it may not be needed.
```
