investigate addition of RTX KG2 to BTE config file

[andrewsu]

Currently, BTE does not issue subqueries to RTX KG2. Enabling that should, in theory, be as simple as adding an entry to our config.js file. Let's test this to see if this is feasible from both the BTE side and RTX side (with the help of @edeutsch and @saramsey).

Glad to help! Our resident experts on the RTX-KG2 API are Eric Deutsch and Amy Glen, and our resident expert on the custom graph database underlying the RTX-KG2 API and on the algorithm that we use to "canonicalize" our knowledge graph, is Amy Glen (who wrote the graph db). I can lend my expertise on any matters pertaining to the pre-canonicalized RTX-KG2 knowledge graph, and of course, I'm willing to facilitate finding an answer for any RTX-KG2-related question for which I don't know the answer.
