Node 14 is EOL

Node 16 will also be EOL (no maintenance) on September 11 2023. As a result, we should upgrade to Node 18.

A part of this migration is updating the version of npm used and updating package-lock.json. npm v7, which ships with Node 16, changed the format of this file. This might cause some complications with npm-force-resolutions, which is a library we use to for all instances of a library to a specified version in the lockfile.

can't update to 18 before the embedded version in VS Code updates too. Currently at 16

well insiders's on 18, so probably for next month

I don't expect we will do a new release before the next VS Code release, unless something urgent comes up
