[URP] Motion vector texture contains outdated info during and before the 'AfterRenderingTrasnparents' injection point
Reproduction steps:
1. Open the attached “ASDQWE” project
2. Open the “Assets/Scenes/SampleScene.unity” Scene
3. Open the Frame Debugger (Window > Analysis > Frame Debugger)
4. In the Frame Debugger Window, press the “Enable” button
5. Observe the “Motion Vectors” rendering event
Expected result: The “Motion Vectors” rendering event is created after the “Render PostProcessing Effects” rendering event
Actual result: The “Render PostProcessing Effects” rendering event occurs after the “Motion Vectors” rendering event
Reproducible with: 2022.3.10f1, 2023.1.17f1, 2023.2.0b14. 2023.3.0a10
Could not test with: 2021.3.31f1 (Two “error CS1061: 'ScriptableRenderer' does not contain a definition for 'cameraColorTargetHandle'“ compilation errors)
Reproducible on: Intel macOS 14
Not reproducible with: No other environment tested

In Unity 2021 LTS, the motion vector texture pass was generated after the skybox is rendered and before transparent objects which makes sense since motion vectors are only generated for opaque objects. However, in Unity 2022 LTS, it runs BeforeRenderPostProcessing which causes problems to any render feature that uses it but needs to run before transparent objects.
This is a regression and should be fixed so motion vectors are immediately available as soon as the opaque objects have rendered.

Resolution Note (fix version 6000.0.0b14):
Motion Vector pass order now correctly follows the Copy Depth pass.
Motion Vectors can now be rendered after Opaques, instead of always rendering after Transparents.
