fix: remove eks encryption config

[wolf31o2]

This is enabled on all clusters for some time. It's not necessary to set anymore.

Summary by cubic

Removed EKS encryption_config from the aws_eks module since cluster encryption is already enabled by default. This simplifies the module and removes a no-op setting.

• Migration
  • Remove encryption_config from any aws_eks module calls.
  • No changes needed on clusters; encryption remains enabled by default.

^{Written for commit 9db44c9. Summary will update automatically on new commits.}

Summary by CodeRabbit

• Refactor
  • Removed encryption configuration support from the EKS module. The encryption_config parameter is no longer available for use when provisioning EKS infrastructure. Users relying on this functionality will need to manage encryption configuration through alternative methods.

📝 Walkthrough

Walkthrough

This change removes the encryption_config variable definition from aws_eks/variables.tf and eliminates the corresponding encryption_config input parameter from the eks module invocation in aws_eks/eks.tf. The modification effectively disables encryption configuration capabilities within the EKS module, with no replacement logic introduced.
