docs: note that timezone-blind cron previews hide DST behaviour

The Cron & Time Intervals page recommends checking expressions in an online 
editor. Most such editors, including the one currently linked, have no timezone 
setting — they show what an expression means in the abstract.

That is a problem specifically for Airflow, because the timezone page documents 
that cron schedules follow DST transitions while timedelta schedules hold a 
fixed UTC time. A reader who verifies `30 2 * * 0` in a timezone-blind editor 
has learned nothing about
what their timezone-aware DAG will do on a transition night, when 02:30 either 
does not exist or happens twice.  This note points that out and 
cross-references the existing timezone page.

Disclosure: I built the tool linked in the note. I have added it as an 
additional reference. The link can be dropped entirely and just the warning can 
be kept if you prefer.
