fix: 1st round of fixes for CSR Test Cases
Review and fixes of the TCs for Context Source Discovery and Context Source Registration (Context Source Registration Subscription is still to be done).
@lopezaguilar I am pretty sure this will break things in the generation of the docs, but don't know what, where and how to fix it. Is there some documentation I can follow to update the scripts accordingly (new keyword, support for a new parameter in an endpoint, new / removed TC, ...)?
