fix: missing immutable setup under type_def

[justin0u0]

This PR fixes an issue where the is_immutable configuration was not being applied to nested fields (e.g. HealthCheckConfig.Type).

Verified using route53-controller. The generator now correctly applies validation markers to immutable nested fields in HealthCheckConfig, resulting in the correct x-kubernetes-validations in the output CRD.

Hi @justin0u0. Thanks for your PR.

I'm waiting for a aws-controllers-k8s member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
