User missing in command

[roelofz]

In response to #2810

@szaimen I think in the following command, the cron user is missing:

*/10 * * * * docker ps --format "{{.Names}}" | grep -q "^nextcloud-aio-nextcloud$" && docker exec --user www-data nextcloud-aio-nextcloud php occ preview:pre-generate

should be

*/10 * * * * root docker ps --format "{{.Names}}" | grep -q "^nextcloud-aio-nextcloud$" && docker exec --user www-data nextcloud-aio-nextcloud php occ preview:pre-generate

Hi, since we recommend to use this command in the guide: sudo crontab -u root -e, I don't think the user is needed here
