My battery got very quickly drained over night after upgrading to Debian bookworm

When upgrading, I forgot that I also upgraded my `/etc/systemd/logind.conf` config file to the latest version which has the following line commented out.

```
# HandleLidSwitch=suspend
```

My battery got completely drained twice. Turned out I just have to uncomment the line, allowing the laptop to enter deep sleep when the lid is closed.
