deps: add missing dependency `resolve`

[jbergstroem]

This is a 🐛 bug fix.

Found while using pnpm - an alternative package manager that is more strict during resolving dependency chains. Guessing it got pulled somehow using when npm.

We require resolve in lib/graph-document.js but is missing from packages.json.
