Fix the link to BFJ

The documentation mentions Big-Friendly JSON (BFJ), but links to an
outdated, archived, GitHub repository
(https://github.com/philbooth/bfj).
A better option would be to link to the NPM package page
(https://www.npmjs.com/package/bfj), in a similar way to how
JSONStream is referenced earlier in the same paragraph.

Closes #2438
