Aspire Storage integration does not work due to ;; part in connection string

### Is there an existing issue for this?

- [x] I have searched the existing issues

### Describe the bug

Looking at: https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting.Azure.Storage/AzureStorageEmulatorConnectionString.cs

the endpoint for emulator ends with ;
```
builder.Append($"{key}={endpoint.Property(EndpointProperty.Scheme)}://{endpoint.Property(EndpointProperty.IPV4Host)}:{endpoint.Property(EndpointProperty.Port)}/devstoreaccount1;");
```

and then the queue connection string gets ;; due to
https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting.Azure.Storage/AzureQueueStorageResource.cs
```
https://github.com/dotnet/aspire/blob/main/src/Aspire.Hosting.Azure.Storage/AzureQueueStorageResource.cs
```

which then ends up with a connection string `xxx;;queuename` and the azure queue service client is not able to parse that.

### Expected Behavior

The expected behavior is that when adding the azure service client to an application that reference the queue, it can connect instead of crashing.
