Use velocity along normal for shuttle impacts (#37667) 

* Use velocity along normal for shuttle impacts

Scrapes shouldn't have the same level of destruction as full-on ramming anymore. Also detecting scrapes should be a lot easier for future stuff.

* Update Content.Server/Shuttles/Systems/ShuttleSystem.Impact.cs
