cron.d file permissions

Hi!
My sprinklers weren't running on the schedule and I found the following error when checking: service cron status
`cron[1072]: (*system*sprinklerd) INSECURE MODE (group/other writable) (/etc/cron.d/sprinklerd)`

I found a fix by running: `sudo chmod 644 /etc/cron.d/sprinklerd`

I'm running on an RPI 4b with with RPI Raspberry Pi OS Lite image + manual install of home bridge & sprinklerd
