job hours are passed as string to cron instead of object

[sergii-sakharov]

E.g. following works:

cron { "curator_${name}":
.....
hour => [2,3,4],
.....
}

While job wraps hour in a string and its now not possible to pass an array. Tried following:
hour: '[3,4,5]'
hour: '3,4,5'

The workaround is to create a job per time slot

Indeed, I just pushed a fix 👍 thanks!
