fix(node): update development nns_url (#3486)

NODE-1560

[wiki.internetcomputer.org](http://wiki.internetcomputer.org/) resolves
to only an IPv4 address (107.161.28.131)

```
$ nslookup wiki.internetcomputer.org
Server:         127.0.0.53
Address:        127.0.0.53#53

Non-authoritative answer:
Name:   wiki.internetcomputer.org
Address: 107.161.28.131
```

This caused bare metal deployment tests to fail when only ipv6 info is
provided. Changing to a more standard url fixes this.
