feat: Add support for deletion protection functionality in the cluster

[tiagovmvieira]

Description

This PR adds support for EKS cluster deletion protection configuration through a new enable_deletion_protection variable. This feature allows users to enable AWS's built-in deletion protection safeguard for EKS clusters, helping prevent accidental or unauthorized deletion of critical infrastructure.

The variable defaults to false to maintain backward compatibility with existing module usage.

Motivation and Context

EKS cluster deletion protection is already a supported feature in AWS, providing a valuable security safeguard that helps prevent accidental deletion of critical Kubernetes infrastructure. This enhancement addresses user requests for better operational safety and aligns with AWS security best practices.

Dependency: This PR requires the AWS Terraform provider to support managing EKS deletion protection through Terraform. While AWS already supports this functionality natively, the Terraform provider implementation is pending in the following PR. This module enhancement will be ready to use once that provider update is released.

Breaking Changes

None. This is a backward-compatible addition. The new enable_deletion_protection variable defaults to false, preserving existing behavior for current module users.
