Nslookup doesn't work in github actions

Hi, I'm trying to access a database from a container with nslookup and I'm getting an error. I've made an example of my github actions to reproduce the error. If I've forgotten anything, please let me know.

The error :
```
Run nslookup postgres

Server: 127.0.0.11
Address: 127.0.0.11:53

** server can't find postgres.psu1waqqpzqu3mj[4](https://github.com/sedeotech/inferni/actions/runs/6588514445/job/17900939871#step:3:4)5gsqnyggvb.xx.internal.cloudapp.net: NXDOMAIN
