Unable to generate CRD with min/max validation for field with int32 alias type #1269
Description
While working on upgrading cert-manager to K8s 1.34, I had to fix an issue in upstream kubernetes-sigs/gateway-api#4044. Now that my PR is merged, but not yet released, I upgraded to a pseudo-version of gateway-api. This last bump introduced commits adding a lot of new markers to API types as part of adopting https://github.com/kubernetes-sigs/kube-api-linter in gateway-api.
And now I am unable to generate the cert-manager CRDs, which include the reuse of upstream Go types from gateway-api.
