### Describe the bug

I'm integrating OpenWebUI by adding it as a Docker container and referencing it in my Aspire application. However, when I try to access it using its container name, the service cannot be resolved.

### Expected Behavior

I expect to be able to access services that are hosted in Docker containers by referencing them using their container names within my Aspire application.

### Steps To Reproduce

In apphost i add container to builder
```csharpIn apphost i add container to builder
```csharp
var openwebui = builder.AddContainer("openwebui", "ghcr.io/open-webui/open-webui", "latest")
.WithHttpEndpoint(3000, 8080, "openwebui");

var opnweb = openwebui.GetEndpoint("openwebui");

builder.AddProject("frontend")
.WithReference(opnweb);
```

In Blazor app, Program cs file, I add this
```csharp
builder.AddServiceDefaults();

builder.Services.AddHttpClient("openwebui", client =>
{
client.BaseAddress = new Uri("http+https://openwebui");
});
```

But every time I tried to access through HttpFactoryClient, i having error address not found
Here i tried to get access to openwebui

```csharp
@page "/counter"
@rendermode InteractiveServer
@inject IHttpClientFactory HttpClientFactory

Counter

Counter

Current count: @models

Click me

@code {
private string models = "";

private async Task IncrementCount()
{
using var http = HttpClientFactory.CreateClient("openwebui");
var response = await http.GetAsync("api/models");
models = await response.Content.ReadAsStringAsync();
}

}
```

When i try to get access to opnweb, to get Host or Port i having error
```
System.InvalidOperationException: The endpoint `openwebui` is not allocated for the resource `openwebui`.
at Aspire.Hosting.ApplicationModel.EndpointReference.get_AllocatedEndpoint() in /_/src/Aspire.Hosting/ApplicationModel/EndpointReference.cs:line …
```

but in environment variables it shows services__openwebui__openwebui__0
