copyfiles is one of the packages that npm audit is unhappy with. Updating to latest to avoid the vulnerability warning.

This will also make us consistent across the repo (currently different versions locked in different build groups).

I don't think so, this was inspired by me getting annoyed during npm i more than a particular threat.
