How to reproduce:
1. Open attached Unity project (hdrp-light-intensity-issue)
2. Load OutdoorsScene
3. Select Sun gameObject
4. Notice intensity is set to 0
5. Enter play mode
6. Notice intensity is still 0
7. In the console window, you can see that light intensity resets after a couple of frames
Expected result: Intensity should be set to 1000.
Actual result: Intensity is set to 1000 for a couple of frames, then resets to 0.

Resolution Note:
This issue is by design. HDRP have its own intensity field that is different from builtin as it rely on physical light unit.
The scripting API to set light is on the HDAdditionalData component: https://docs.unity3d.com/Packages/com.unity.render-pipelines.high-definition@7.1/api/UnityEngine.Rendering.HighDefinition.HDAdditionalLightData.html?_ga=2.187700392.1256829761.1644225368-683797712.1641845328#UnityEngine_Rendering_HighDefinition_HDAdditionalLightData_intensity
