leggings info for chestplate code

[lunarwolf2008]

Issue: on the custom armor page at the adding attachables section, it provides code for a chestplate, but then the description of code is for leggings as well as the example textures are leggings

Page:https://wiki.bedrock.dev/items/custom-armor.html

Suggestions: change it to be a chestplate texture and discription
