doc: reword possessive form of Node.js in zlib.md

Throughout the docs, we sometimes write the possessive of _Node.js_ as _Node.js'_ and other times as _Node.js's_. The former conforms with some generally accepted style guides (e.g., Associated Press Stylebook) while the latter complies with others (e.g., Chicago Manual of Style). Since there is no clear authoritative answer as to which form is correct, and since (at least to me) both are visually jarring and sometimes cause a pause to understand, I'd like to reword things to eliminate the possessive form where possible. This is one of those examples.
