Kusto emulator health check fails on MacOS

```C#
var kde = builder.AddAzureKustoCluster("kusto").RunAsEmulator()
.AddReadWriteDatabase("My95App");

var apiService = builder.AddProject("apiservice")
.WithHttpHealthCheck("/health")
.WithReference(kde);
```

**Bug Summary:**
The Kusto emulator health check consistently fails to report healthy status when running on MacOS.

**Details:**
- Exception stack trace:

```
Kusto.Data.Exceptions.KustoClientException: Kusto client failed to send a request to the service: 'The response ended prematurely. (ResponseEnded)'.
Error details:
DataSource='http://localhost:56702/v1/rest/mgmt',

at Aspire.Hosting.Azure.Kusto.AzureKustoHealthCheck.CheckHealthAsync(HealthCheckContext context, CancellationToken cancellationToken) in /_/src/Aspire.Hosting.Azure.Kusto/AzureKustoHealthCheck.cs:line 33
```

**Steps to Reproduce:**
1. Run Aspire project with Kusto emulator on MacOS.
2. Observe health check status (never goes healthy).

**Expected Behavior:**
Kusto emulator should pass the health check if the emulator is running and accessible on MacOS.

**Environment:**
- MacOS
- Please add your .NET SDK/runtime version

**Additional Information:**
- Health check code: `src/Aspire.Hosting.Azure.Kusto/AzureKustoHealthCheck.cs`
- Emulator setup code: `src/Aspire.Hosting.Azure.Kusto/AzureKustoBuilderExtensions.cs`
- Functional tests: `tests/Aspire.Hosting.Azure.Kusto.Tests/KustoFunctionalTests.cs`
- Emulator container image: `src/Aspire.Hosting.Azure.Kusto/AzureKustoEmulatorContainerImageTags.cs`
