Here.I don't know of there being a translation section myself on the wiki..but it's a great idea! You might toss that question to @steemcenterwiki in their steemit.chat channel:
There is also operation translation available on any of my guide/faq posts as well as many that @papa-pepper and @stellabelle had done in the past (not sure if that's still current. I don't wanna speak for them.) While not paid directly, you get to keep all earnings from the post. The only ask is a link back to the original.
