Subject: [PATCH] Fix misleading modified status of scenes

If a scene is instanced in another scene, any changes to the first
triggers _clear_undo_history in EditorNode::set_current_scene, which
increments the version in UndoRedo::clear_history. This results in a
modified status. Passing false to clear_history fixes this issue.
Fixes #25942
