The entry for harpsichord currently on UMIL is actually a specific harpsichord

I was intrigued by the fact that the UMIL page for harpsichord doesn't have a French label, and it turns out that's because it's a Wikidata entry for a [specific harpsichord](https://www.wikidata.org/wiki/Q89189756), built by a certain Alessandro Trasuntino in Venice in 1531 and now part of the collection of the Royal College of Music. That entry is only in English, because only the RCM cares about it. The Wikidata page for the instrument harpsichord is [this one](https://www.wikidata.org/wiki/Q81982) and it has a bajillion language labels, which makes more sense.

If you look up "harpsichord" on wikidata, the first result that comes up is the general page for harpsichord, but the ones right after that are specific instruments from museum collections, like the one that ended up on UMIL.
In fact, the same thing happened with the clavicytherium: [this](https://www.wikidata.org/wiki/Q61324520) is the instrument on UMIL and [this](https://www.wikidata.org/wiki/Q1746064) is the general clavicytherium page.

I bring this up because there are a lot or wikidata pages just like this, that have the same name as a general instrument page but are actually a specific instrument, usually a museum piece. This ties in to @kyrieb-ekat and @dchiller's [excellent discussion](https://github.com/DDMAL/UMIL/issues/336) about determining what is and isn't an instrument. At one point does a museum piece become its own instrument?
