Update CITATION.bib to remove entanglement forging authors (#583)

This is a follow up to #580.  This removes six additional authors
who only contributed to entanglement forging and have made no
direct contributions to circuit cutting to the best of my
knowledge.

I've also reformatted with one author per line.

(cherry picked from commit 586e50f)
