We are currently implementing this feature for both the SkeletonAnimation and SkeletonMecanim component workflow (it is called Root Motion as common terminology). You can subscribe to the issue ticket to get notified upon updates: https://github.com/EsotericSoftware/spine-runtimes/issues/1417
In the meantime, you can use the experimental component by Pharan below that was adapted to spine-unity 3.8 (with some minor changes). But note that this script will not work with SkeletonMecanim, only with SkeletonAnimation.
