Add JSON products to CL's description. (#2665)

* Add JSON products to CL's description.

Update CL's description to add the JSON version of the main, -basic, and
-base products.

Also remove the dependency to CHEBI, which is incorrect: CL does not
import CHEBI.

* Fix sort order of CL dependencies.
