On https://www.minecraft.net/en-us/msaprofile/mygames/editskin, underneath the skin chooser, is a paragraph that says "Do you wonder HOW you give your character a unique texture? Create your own skin or find ready-made skins on the internet! Check out this help article for more information."
This "help article" goes to https://help.minecraft.net/hc/en-us which isn't a help article. It should possibly go to https://help.minecraft.net/hc/en-us/articles/4408894664461-Minecraft-Java-Edition-Skins instead.
This issue still persists though the menu itself has been changed. For some reason the link you said would be good to add was added but to the "For more information, check this handy help article" link.
