### Describe the bug

After upgrading to Aspire 13.5, the dashboard's Graph view throws an unhandled exception whenever a resource uses `storage.AddBlobs("blobs")`. The resources table view still works fine, only the graph view breaks.

### Expected Behavior

Graph is working

### Steps To Reproduce

```
var builder = DistributedApplication.CreateBuilder(args);

var storage = builder
.AddAzureStorage("storage")
.RunAsEmulator(azurite => azurite.WithDataVolume());

storage.AddBlobs("blobs");

builder.Build().Run();
```

Reproduce the issue with the supplied AppHost and inspect Aspire.Dashboard/Model/ResourceGraph/ResourceGraphMapper.cs around GetIconPathData at line 90. Trace how Resources.razor.cs updates graph resources around lines 393-406 and identify why the blob resource produces invalid icon XML. Done means the Graph view renders successfully with storage.AddBlobs("blobs") without an unhandled exception.
