Description

This PR updates the configuration for webpack-dev-server, to avoid a fatal error when trying to start it:

$ yarn webpack-dev-server
yarn run v1.22.19
$ webpack-dev-server
[webpack-cli] Invalid options object. Dev Server has been initialized using an options object that does not
match the API schema.
 - options has an unknown property 'stats'. These properties are valid:
   object { allowedHosts?, bonjour?, client?, compress?, devMiddleware?, headers?, historyApiFallback?, host?,
hot?, http2?, https?, ipc?, liveReload?, magicHtml?, onAfterSetupMiddleware?, onBeforeSetupMiddleware?,
onListening?, open?, port?, proxy?, server?, setupExitSignals?, setupMiddlewares?, static?, watchFiles?,
webSocketServer? }
error Command failed with exit code 2.

How is this tested?

• Manually

With the updated configuration in this PR, webpack-dev-server works again:

$ yarn webpack-dev-server
yarn run v1.22.19
$ webpack-dev-server

Meh, I'm just going to merge this. It's fixing a current non-working situation. We can adjust things later on if it turns out to need it. 😄
