Consider adding a reference to Cron format which does not require navigating away #546
Description
Problem
Users somewhat familiar with Cron wanted to use it but did not remember the syntax. Working in environments without internet access they could not open the link to https://www.gnu.org/software/mcron/manual/html_node/Crontab-file.html available in the UI.
Proposed solution
Add a small reference example:
| Current | Proposed |
|---|---|
 |
 * |
- existing link can stay or be removed; please ignore non-matching "Interval" definition on figma snapshot.
