add colocation information

[WolfgangFahl]

CEUR-WS is one of the inputs that may provide metadata for the colocated property as outlined in WDscholia/scholia#2174 see also https://docs.google.com/document/d/1cnYoFFtasDM7H7DuRcLmwl_41K-lYL9C6o5SoJHKvmA/edit#heading=h.gjdgxs for the definition

@ ISWC 2022

which has been published as CEUR-WS Volume https://ceur-ws.org/Vol-3262/

Action
Find out the conference the workshop has been colocated with and check wikidata for
having the correct property - if not add it.

Proceedings of the 12th International Workshop on Satisfiability Modulo Theories
affiliated with
the 26th International Conference on Computer Aided Verification ([CAV 2014](http://cavconference.org/)),
the 7th International Joint Conference on Automated Reasoning ([IJCAR 2014](http://cs.nyu.edu/ijcar2014/)), and
the 17th International Conference on Theory and Applications of Satisfiability Testing ([SAT 2014](http://baldur.iti.kit.edu/sat2014/)).

Action:
