Scheduler : crontab configuration is missing

[Ribero]

The crontab of the container based on the official docker image is missing the crontab configuration see issue getgrav/grav#3153

(crontab -l; echo "* * * * * cd /var/www/html;/usr/local/bin/php bin/grav scheduler 1>> /dev/null 2>&1") | crontab -

it would be nice if this command could be added to the default configuration.

While I was looking at the build of the image I saw in the console:

Step 12/15 : RUN (crontab -l; echo "* * * * * cd /var/www/html;/usr/local/bin/php bin/grav scheduler 1>> /dev/null 2>&1") | crontab -

**no crontab for www-data**

The configuration is "missing" for root user but the scheduler must not run as root.

The crontab for www-data user is present but was not working.

Removing the crontab for this user then re-adding solved the issue for me. See #3153

I just tried to build the image, still the same error
