Use ISO 8601 year-month-day format for ISO releases

[qx-775]

Hi,

When visiting the downloads page on blackarch.org to download the released ISO's it shows the version date as 2021.09.01 which confused me. How can ISO's be released on the first of september in 2021 when its only august of 2021?

I believed this ISO date to be in the official year/month/day format as not everyone uses United States based date format.
Could you change this to a format which is universally accepted - using ISO 8601 format ?

This small change will help small confusions.
