Adventure Idea: Infrastructure as Code with OpenTofu on AWS

Overview

This PR adds a new adventure idea for learning Infrastructure as Code fundamentals using OpenTofu on AWS. The adventure places learners in the role of a DevOps engineer who needs to standardize cloud infrastructure deployment.

What Makes This a Good Adventure?

✅ Action-oriented: Focuses on what learners do (deploy, verify, destroy) rather than just learning a tool
✅ Progressive: Single well-scoped beginner level that introduces core concepts
✅ Practical: Uses AWS Free Tier with clear instructions to avoid costs
✅ Verifiable: Clear objectives that can be checked (VPC creation, RDS in private subnets)
✅ Real-world: DevOps scenario that reflects actual job requirements

Learning Objectives

By completing this adventure, learners will:

• Write and apply Infrastructure as Code with OpenTofu
• Deploy VPC, EC2, RDS, and S3 resources on AWS
• Understand OpenTofu workflow (init, plan, apply, destroy)
• Manage infrastructure state
• Destroy resources to avoid ongoing costs

Tools & Technologies

• OpenTofu (Terraform fork)
• AWS (VPC, EC2, RDS, S3)
• AWS CLI
• Git

Checklist

• Action-oriented skills (deploy, verify, destroy)
• Clear prerequisites and tools
• Verifiable objectives
• Cost considerations included
• Real-world story/theme
• Follows adventure idea template

Closes #26

Hi Junaid,

first of all thanks for the contribution! I was really excited when I saw your PR a couple of minutes ago 😊

I like the direction you're heading to but if I understand it correctly the idea sounds very similar to what we had in adventure 2. May I ask you to provide more information on how this is different from the learnings in the previous adventure? This could also be further levels where the learning path diverges from what we previously had.
