etcd-snapshot-cron flag help text incorrect

[brandond]

• From @akose73 in Fix cronjob example rancher/rke2-docs#38:

In the case of "* */5 * * *", it runs every minute past every 5 hours, so it is not true that it runs every 5 hours.
To solve it set 0 as minutes (0 */5 * * *)

[VestigeJ]

This validation isn't super serious because both the previous and now the new example for cron are valid cron schedules.
