ER: update chron instructions and behavior

### Overview
We need to revise the formatting of the chron to account for daylight savings time, and we need to write a prompt for the installers/configurers of the PRs to use in ChatGPT to create the day/time they want

#### Details
Example
on:
schedule:
# PDT (UTC-7) → 5 PM Tuesday = 00:00 Wednesday UTC
- cron: '0 0 * 1-6,8-11 3'

# PST (UTC-8) → 5 PM Tuesday = 01:00 Wednesday UTC
- cron: '0 1 * 1-6,8-11 3'

Start by reviewing the linked ChatGPT conversation and the current chron instructions and behavior in the automate-the-org repository. Confirm how daylight-saving changes should affect the cron examples, then define the installer/configurer prompt. Done means the instructions and behavior reflect the required PDT/PST scheduling and the prompt is included.
