Update wowchemy paths in Update page.

[EricMcKinney77]

I tried to follow the steps in the Hugo Blox Update page (https://bootstrap.hugoblox.com/hugo-tutorials/update/), but I got an error when I tried to add the import paths to my config.yaml. The error stated that the wowchemy paths do not exist. I think I found the correct paths, but I'm not sure. It seems like the Update page needs to be updated. 🙂
