Schedule builds to update packages regularly
based on discussion in !3 (closed)
Tried to achieve this in riseuplabs/docker: https://0xacab.org/riseuplabs/docker/pipeline_schedules
Turns out it does not work due to the docker caching logic. If the Dockerfile does not change at all it will also cache 'apt update' and the like. The caching can be disabled with a flag - which is what i planned to do for the scheduled builds next. Micah proposed to use a cron job in !3 (closed). Not sure which path we want to follow here.
