fix fogbugz 989321 - Light broken when created as "Area" light

ScriptableRenderPipeline/HDRenderPipeline/HDRP/Lighting/Light/HDAdditionalLightData.cs

         // As we have our own default value, we need to initialize the light intensity correctly
         public static void InitDefaultHDAdditionalLightData(HDAdditionalLightData lightData)

-            // At first init we need to initialize correctly the default value
-            lightData.ConvertPhysicalLightIntensityToLightIntensity();

-            // Special treatment for Unity builtin area light. Change it to our rectangle light

+            // Special treatment for Unity built-in area light. Change it to our rectangle light
             var light = lightData.gameObject.GetComponent<Light>();
 
             // Sanity check: lightData.lightTypeExtent is init to LightTypeExtent.Punctual (in case for unknow reasons we recreate additional data on an existing line)
                 light.type = LightType.Point; // Same as in HDLightEditor
