Village pathways should use stairs

Super-tall mountains generate in the 1.18 caves and cliffs update. Sometimes villages spawn at those mountains or in hilly terrains and their pathways get displaced by the terrain. Sometimes there is a 2 block or higher y level displacement in the pathway in villages, especially ones that spawn at mountains or hilly terrains, and villages cannot traverse the pathway easily. To solve that, there should be stairs that connect the pathways.
