github: Add cron job for refreshing TUF timestamp

This will run every hours. It will call a script: https://github.com/foundriesio/fioctl/blob/tuf-metadata/refresh-metadata.sh That will check if the timestamp is expiring in the next 48 hours. If so, it will update the timestamp for another 7 days. Signed-off-by: Andy Doan <[email protected]>
