fix: remove cubicweb-signedrequest from recommends

This is needed as rqlcontroller is listed as deps in signedrequest.
This creates the following error in signedrequest:

cubicweb._exceptions.ConfigurationError: cycles in graph: rqlcontroller -> signedrequest

This is cubicweb related and not a cycle in deps directly.
