Attempt to fix builds by configuring Karma listenAddress

### Why?

```
07 08 2023 18:16:36.397:INFO [karma-server]: Karma v6.4.2 server started at http://localhost:9876/
07 08 2023 18:16:36.398:INFO [launcher]: Launching browsers jsdom with concurrency unlimited
07 08 2023 18:16:36.402:INFO [launcher]: Starting browser jsdom
07 08 2023 18:16:36.421:ERROR [karma-server]: UnhandledRejection: Error: connect ECONNREFUSED ::1:9876
    at TCPConnectWrap.afterConnect [as oncomplete] (node:net:1495:16)

```

> The Karma server only listens on IPv4 address (`0.0.0.0`) by default,
> but the requests are sent to `localhost` and `localhost` is resolved
> into IPv6 address (`::`) in Node 17+. So the run request is unable to
> reach the Karma server.
