Add test dataset for trec tip of the tongue dataset

[mam10eks]

The test queries for the trec tot task are now available, and this pull request adds them in a similar way to how they are added for dev and train (no qrels are available yet, we can also wait to merge this until the qrels are available).

Thanks! A few points:

• Can we rename it to trec-tot/2023/test? This is more aligned with the typical naming convention.
• Are the sentence_annotations of a standard structure? If so, they should be represented as NamedTuples instead of dicts.
• Can you add a metadata record and documentation for this dataset? (This is why the tests failed.)
