Add support for accessing the Translator Test Harness tests

[gaurav]

They contain InputName - InputID pairs, so we can use that to check whether e.g. searching for Multiple Sclerosis gives us MONDO:0005301 as the top result.

(I don't want to share the link to the Translator Test Harness here, but it is in the TAQA meeting notes for Jan 12, 2024.)
