Wrong validation for Version.EB

[icromme]

assert CronValidator.parse('* * * * 7', version=Version.EB) gives error but reference "The cron validator supports partially extended rules based on the Amazon EvenBridge rule set" to https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-cron-expressions.html says "Day-of-week = 1-7 or SUN-SAT"
