[Playables] The first frame of the Animation Playable is delayed when entering Play Mode causing a delay by one frame

Animation

-

How to reproduce it:
1. Open the project "animationProject"
2. Open the scene "SampleScene"
3. Press the Pause button
4. Press the Play button
5. Press the Step button a few times
6. Observe the first lines in the Console window

Expected result: after the first execution of Update method the local time of the Playable changes
Actual result: after the first execution of Update method the local time of the Playable is the same

    Resolution Note (fix version 2021.2):

    As we update the time of the playables in the PreLateUpdate method callback, it is normal to always have a difference of time of one frame between the Update and LateUpdate methods (see : https://docs.unity3d.com/Manual/ExecutionOrder.html).
    The documentation was updated for the SetTime and GetTime of playables
