Fix README: Enabling/starting systemd unit (#69)

Browse Source 
systemctl start restic-backup@default.timer was failing with the following message:

```console
❯ sudo systemctl start restic-backup@default.timer
Failed to start restic-backup@default.timer: Unit nm-unmetered-connection.service failed to load properly, please adjust/correct and reload service manager: Device or resource busy
See system logs and 'systemctl status restic-backup@default.timer' for details.
```

and by doing `systemctl daemon-reload` before that command solved the issue.

But according to `man systemd` in order to avoid this, it seems that `enable` command must be issued before `start`, as it reloads the system manager configuration (in a way equivalent to daemon-reload). So, once properly sorted, it seems that both commands can be fused into a single `enable --now` command :)
