feat(terraform): Structure Code for Multiple Environments

[carlagesa]

To ensure stability and safe testing, our infrastructure should be replicated across different environments (e.g., dev, prod). We need to structure our Terraform project to support this. A common approach is to use separate directories or workspaces for each environment, which allows us to manage their configurations and state independently while reusing the same core modules.

Acceptance Criteria:

• A directory structure is created to manage at least two environments (e.g., environments/dev and environments/prod).
• Each environment has its own main.tf and .tfvars file to manage environment-specific configurations.
• The CI/CD pipeline is updated to allow deployments to a specific environment.
