Have a challenge with a backup bucket containing the secret

Context

• What should the challenge scenario be like? Have a backup s3/storage bucket with a private ed25519 key publicly exposed
• What should the participant learn from completing the challenge? Secure your backup at all cost
• For what category would the challenge be? (e.g. Docker, K8s, binary) Docker/cloud depending on how we implement the backup solution

Actions:

• create separate Terraform folder to have an S3 bucket (in our AWS folder) under the name "backupchallenge"
• have the key copying logic in a shell script using AWS CLI as part of the backupchallenge folder
• implement the challenge according to contributing.md and make sure you hide the key in your classfile.
