"Can't change name, category with the same name already exists" Error is logged when renaming a Category to a name with a trailing space in the VFX Graph Blackboard

Steps to reproduce:

1. Create a URP 3D project with the Visual Effect Graph package installed
2. Create a Visual Effect Graph asset and open it
3. In the Blackboard, create a Category (e.g. "MyCategory")
4. Rename the Category to a name ending with a space (e.g. "MyCategory ")
5. Press Enter and observe the Console

Actual results:

The Console logs: "Can't change name, category with the same name already exists"
(with a UnityEditor.GUIView:ProcessEvent stack), even though no other category has
that name.

The Category is still renamed (the trailing space is trimmed).

Expected results:

Renaming a Category to a name with a trailing space trims it silently and
applies the rename without a false Error
