fix: correct Slack webhook example code in documentation

jasonwbarnett · jasonwbarnett · commit 578f3e981c2f · 2025-12-16T10:55:45.000-07:00
- Fix ReferenceError by changing 'text: body' to 'text: body_markdown' on line 118
  (the variable 'body' was never defined; should use 'body_markdown' from req.body)
- Fix invalid_blocks API error by changing header block text type from 'mrkdwn' to 'plain_text' on line 122
  (Slack's header block type only supports plain_text, not mrkdwn)
- Rename 'title_markdown' to 'title' since the header block uses plain_text type, not markdown
  (variable names should reflect their actual content)

These errors were preventing webhook messages from being sent to Slack.
