Incorrect document in the readme

[toddb]

Thanks for the work.

The readme incorrect shows needing to use cron( ... ). Instead only the expression is required.

/* Start the RDS cluster at 6:50am EDT Monday - Friday */
up_schedule    = "cron(50 10 ? * MON-FRI *)"
/* Stop the RDS cluster at 9pm EDT every night */
down_schedule  = "cron(0 1 * * ? *)"

This errors

/* Start the RDS cluster at 6:50am EDT Monday - Friday */
up_schedule    = "50 10 ? * MON-FRI *"
/* Stop the RDS cluster at 9pm EDT every night */
down_schedule  = "0 1 * * ? *"

You may also want to add a link to the cron syntax: // cron syntax https://docs.aws.amazon.com/AmazonCloudWatch/latest/events/ScheduledEvents.html
