[unity] Added previously missing unlit URP 2D shader variant `Universal Render Pipeline/2D/Spine/Skeleton`.

   * Added `Spine/SkeletonGraphic Fill` shader to provide functionality of `Spine/Skeleton Fill` shader for `SkeletonGraphic`.
   * Lit Spine URP shaders (`Universal Render Pipeline/Spine/Sprite` and `Universal Render Pipeline/Spine/Skeleton Lit`) now support `Forward+` rendering path as introduced by Unity 2022.2 and URP version 14.
   * `SkeletonGraphic` now supports automatic scaling based on its `RectTransform` bounds. Automatic scaling can be enabled by setting the added `Layout Scale Mode` Inspector property to either `Width Controls Height`, `Height Controls Width`, `FitInParent` or `EnvelopeParent`. It is set to `None` by default to keep previous behaviour and avoid breaking existing projects. To modify the reference layout bounds, hit the additional `Edit Layout Bounds` toggle button to switch into edit mode, adjust the bounds or hit `Match RectTransform with Mesh`, and hit the button again when done adjusting. The skeleton will now be scaled accordingly to fit the reference layout bounds to the object's `RectTransform`.
+  * Added previously missing unlit URP 2D shader variant, available under `Universal Render Pipeline/2D/Spine/Skeleton`.
  
 * **Breaking changes**
   * Made `SkeletonGraphic.unscaledTime` parameter protected, use the new property `UnscaledTime` instead.
