Workflows

Name	Description
terraform-ci.yaml	A workflow for linting and auto-formatting Terraform code. Triggered by pushes to main and dev branches or on pull requests, it consists of two jobs: tflint for lint checks, format for code formatting and submit a PR, and tfmermaid to update architecture graph and submit a PR.
