Description

For reasons that are beyond me, enabled_cluster_log_types is a list of strings normally, but when there's a dynamic block added to the resource it becomes a list of list of strings. This PR adds tests to confirm that this is indeed an issue (if you run the test file against the check in master then it fails on aws_eks_cluster.fully_enabled_with_dynamic_block), and fixes the issue by checking the type before itterating.

Generated description

Dear maintainer, below is a concise technical summary of the changes proposed in this PR:

Address an issue in the EKSControlPlaneLogging class where the enabled_cluster_log_types configuration can be a list of lists when a dynamic block is present. This pull request modifies the logic to correctly evaluate the configuration by checking the type before iterating. Additionally, new test cases are added in test_EKSControlPlaneLogging.py to ensure the fix is effective, including scenarios with dynamic blocks.
