Feature Request: Add cron and specific call for invoice reminders

[gromain]

Hello,

I've been using this docker image for a few months and it works perfectly! There is only one thing bugging me and that is the fact that this image is not set up to send emails automatically.

Is it possible to add cron and the following string to its crontab: * * * * * php /var/www/html/artisan schedule:run >> /dev/null 2>&1?
