Pull request overview

Adds a new Terraform module under aws/eks-addon to manage a single EKS addon, aligning with the existing aws/eks-addons (multi-addon) module structure and conventions.

Changes:

• Introduces a new aws/eks-addon module with inputs for addon name/version, cluster name, configuration values, and IAM role ARN.
• Implements standard tagging via locals.interpolated_tags and a time_static timestamp.
• Adds generated module documentation (README.md) and module-local tflint configuration.
