New review comment by meator on void-packages repository

https://github.com/void-linux/void-packages/pull/48854#discussion_r1497046839

Comment:
```
xbps-query -RX power-profiles-daemon
```

lists `gnome` as the only reverse dependency. Is `power-profiles-daemon` an optional dependency in KDE?

I have mentioned only GNOME in the README because that's what upstream warns about.
