chore: update comment about skipping the DHT test

To find all of those comments run:

```console
$ grep DHT test -R |grep TODO
test/cli/dht.js:// TODO: unskip when DHT is enabled: #1994
test/core/ping.spec.js:  // TODO: unskip when DHT is enabled: #1994
test/core/interface.spec.js:      reason: 'TODO: unskip when DHT is enabled: #1994'
test/core/dht.spec.js:// TODO: unskip when DHT is enabled: #1994
test/core/name.spec.js:  // TODO: unskip when DHT is enabled: #1994
test/http-api/inject/dht.js:  // TODO: unskip when DHT is enabled: #1994
test/http-api/interface.js:      reason: 'TODO: unskip when DHT is enabled: #1994'
```
