Error: WebSocket Servers can not be created in the browser!

# Description

The basic example worked as expected. But when I tried to add custom listen multiaddrs, I got an error:

```diff
const node = await createLibp2p({
+ addresses: {
+ listen: ["/ip4/0.0.0.0/tcp/8004", "/ip4/0.0.0.0/tcp/8003/ws"],
+ },
transports: [
circuitRelayTransport({
discoverRelays: 1,
}),
...
```

```
