[Request] "jurisprudence" as an alias for entrytype "jurisdiction"

[alercah]

I am not sure how jurisdiction came to be the entrytype for case law, but it is the wrong word. The correct word is jurisprudence.

Therefore I would propose adding jurisprudence as an alias for jurisdiction as an entrytype.

Hmm, I guess it was just a bad translation from German (assuming PL added the type). I'm wondering, though, if we really should get involved here by adding jurisprudence and deprecating jurisdiction. The standard styles don't do anything special for these types anyway.

@plk What do you think? It think it is useful to have sensibly-named entry types in the data model. But I don't want to rush unnecessary changes to the data model.

I think it's fine to add a driver source map for this.
