Mismatches within (zombie) villager textures

A bunch of villagers have a mismatch between the leg textures' sizes and top/bottom.

See images. The top of the legs should match the color of the top of the sizes of the legs, and the bottom of the legs the bottom of the sizes of the legs.

The base skins are also affected. (The zombie villager base skin matches relatively well, but there's a huge contrast still, if the bottoms of the legs and arms were made lighter, this would not be such a big issue.)

Additionally, the desert villagers' arms' inside is a solid color, unlike every other villager's.

Note about the images: I made them a while ago with textures from an older version, BUT, the issues that I highlight in this report are still present in current day versions.
