fix: typesafety of Node and Edge changes

On some functions and type definitions related to Change Events,
the generics for the types Node and Edge were being lost.

This commit fixes those:
  - Functions
    - applyNodeChanges
    - applyEdgeChanges
  - Types
    - NodeChange
    - EdgeChange
    - OnNodesChange
    - OnEdgesChange
