Drop wrong api_wrappers from modules README.md

There is no api_wrappers folder inside this folder.

The api_wrappers folder is in the sourced folder, not the modules folder.

The AWS link is invalid, empty. Wolfram Alpha exists under the sourced/api_wrappers folder, where it was moved to from a root api_wrappers folder in c47ccd4.
