[External PR] Fix incorrect license identifier in package.json

See title; the distributed LICENSE file and copyright blurb in most files list a seemingly innocent, but important distinction from the standard BSD-3-Clause license. Someone with access can pull from https://git.sr.ht/~jlicht/dhive on master if you want to just lazily grab my 'fix'.

What makes this story even more silly is that dhive is listed as an example of this license on spdx.org

Sadly, this does make it so that dhive does not appear to be Open Source software according the the OSI definition, but (arguably) it would be Ethical Source instead.
