Upgrade guide for Grid v7.2.2

Deprecated DomSync.removeChild() in favor of DomSync.remove()

The static method DomSync.removeChild(parentElement, childElement) is now deprecated. Use DomSync.remove(childElement) instead, which derives the parent automatically and works correctly for descendant elements (not just direct children).

Old code

DomSync.removeChild(parentElement, childElement);

New code

DomSync.remove(childElement);
