Goal

User story
As a new user reading the docs,
I want to browse tutorials that focus only on the most essential onboarding content.

How

• Update /docs/get-started/tutorials-and-guides to only include the most essential onboarding guides.
• Talk to @zayhanlon to figure out which (if any) of our guides address the topics that the CS team covers for onboarding.
