chore: pin and update Node.js and some deps (#630)

* chore: add nvmrc and update package-lock.json

* chore: update CI to Node 16

* doc: document Node.JS version

* chore: npm audit fix (non-breaking)

* chore: update browserlist

* chore: run npm audit fix --forge

This updates node-forge and webpack-dev-server in package.json,
and many others in package-lock.json.

Update webpack-dev-server config due to some deprecated options.

* minor: add comma
