OData.Client throws ArgumentException

### Description

When using OData.Client nuget package (https://www.nuget.org/packages/Microsoft.OData.Client/) on MacCatalyst or iOS with MAUI, application throws `System.ArgumentException` while executing query on OData context. Other platforms (Android, Windows) behave as expected - return queried data.
Exception message tells that the key has been already added. In my case I was able to spot two keys, causing problem:
- OData-Version
- X-AspNet-Version

I tested this with local API and I can tell that HTTP call reaches WebAPI endpoint, so I guess the problem is in response processing.

Exception message: "An item with the same key has already been added. Key: X-AspNet-Version"

### Steps to Reproduce
Using provided example repo:

1. Run _testOdataMaui_ project on MacCatalyst or iOS.
2. Click "Click Me" button.
3. Exception will be displayed via Alert modal.
4. Mac Catalyst project also avaliable in _odataMacCatalystExample_ project

### Expected Behavior
OData client executes query without exception.

### Actual Behavior
OData Client throws exception on iOS and Mac Catalyst platforms.

```shell
Exception message: "An item with the same key has already been added. Key: X-AspNet-Version"
