Michel Weststrate 4ada403841 generate-changelog.js should be Node 6 compatible
Summary:
Node on SandCastle is ancient, this change makes sure we can use the node version of `www`.

Node 6 can't parse dangling comma's in argument lists, which is what prettier automatically inserts by fbsource standards
