Upgrade webpack-dev-server dependencies

Reinstall webpack-dev-server, to force an upgrade of its dependencies. Node 18 is crashing because of a crashing bug in memfs 3.4.1, which is a dependency of webpack-dev-middleware.

LGTM.

As noted in Slack removing host: process.env.HOST || 'localhost' from webpack.dev.js is required to run PFE locally (one of PR review checklist items).
