Option for Compact Slack Notifications

### Problem Statement

Notifications in Slack can contain too much information, especially when receiving multiple notifications in a row, would like the option for a compact view.

### Solution Brainstorm

Add a toggle for compact views, only include basic information, like error name and a link?

### Product Area

Settings - Integrations

Start in the Settings - Integrations area and trace the existing Slack notification flow; the issue names no files or tests, so identify those first. Done means users can toggle compact Slack notifications and receive only the basic information described, such as the error name and a link.
