[Mac Catalyst] Geolocation.GetLocationAsync() is null in MacOs

### Description

When this code is executed:
```
try
{

var request = new GeolocationRequest(GeolocationAccuracy.Medium, TimeSpan.FromSeconds(10));
#if IOS || MACCATALYST
request.RequestFullAccuracy = true;
#endif
CancellationTokenSource cts = new CancellationTokenSource();
var location = await Geolocation.GetLocationAsync(request, cts.Token);
if (location != null)
{
Console.WriteLine($"Latitude: {location.Latitude}, Longitude: {location.Longitude}, Altitude: {location.Altitude}");
}
return location;
}
catch (FeatureNotSupportedException fnsEx)
{
// Handle not supported on device exception
return null;
}
catch (FeatureNotEnabledException fneEx)
{
// Handle not enabled on device exception
return null;
}
catch (PermissionException pEx)
{
// Handle permission exception
return null;
}
catch (Exception ex)
{
// Unable to get location
return null;
}
```
The variable location always is null. the variable location works in platforms: android, ios. windows I haven't tried it.

i have this permissions:
```
NSLocationTemporaryUsageDescriptionDictionary

TemporaryFullAccuracyUsageDescription
Fill in a reason why your app needs full accuracy

NSLocationUsageDescription
Fill in a reason why your app needs access to location.
NSLocationWhenInUseUsageDescription
