[[FIX]] Update Lodash to latest 4.17.19 (#3494)

Address vulnerability of type "Prototype Pollution in lodash" GHSA-p6mc-m468-83gw

It is not sure whether this is at all relevant for jshint, but at the moment, GitHub's Dependabot sends vulnerability alerts to all respositories with a dependency to jshint, e.g.
https://github.com/alexandrainst/node-red-contrib-parser-ini/network/alert/package-lock.json/lodash/open

So it would be nice to issue a new jshint release ASAP to offer an easy way forward for those projects with a (dev) dependency to jshint.
