Look at useEntityBlockEditor

Gutenberg now has a `useEntityBlockEditor` which seems to provide much of the undo/redo functionality. It does require that data uses post entities, so it's worth investigating to see if it can replace the custom undo history code.

Start by reading Gutenberg's useEntityBlockEditor and compare its requirements with the existing custom undo history code. Determine whether the editor's data can use post entities and whether the hook can replace the current history implementation; done means documenting that feasibility and any required follow-up changes.
