Change comments for examples_star_json build target

@gingerik, what do you think?
You quoted only the end of the doc sentence. The first part, and the previous sentence are important. 

`oli.js` and `olx.js` do not use `goog.provide` or `goog.require` so `closure-util` will not include these files as a result of resolving dependencies. This is the reason we need to bypass `closure-util`, and use the `"js"` compile property instead (with `manage_closure_dependencies`).

Hope it makes sense this time.
