always use ValidationMethod=DNS (#13)

Not sure when, but at some point in the past year or so, the code generator was changed in a way that when you add fields to the `ignore` list, that field is literally `delete`d from the associated `aws-sdk-go/private/model/api.Shape` object. This means that you cannot have *both* a field that is in the `ignore` list (because you don't want it to appear in the CRD's fields) *AND* have that field referenced in the `override_values` map for an `Operation`. Because the code that sets an Input shape for an Operation iterates over the Input shape's `MemberNames()` collection, and the code generator has literally `delete`d the ignored field from the shape, meaning it cannot be referenced in the override_values code :(

This fixes an issue in the ACM controller where the `generator.yaml` file had the ValidationMethod field both ignored and in override_values by adding a `sdk_create_post_build_request` hook that manually sets the `RequestCertificateInput.ValidationMethod` field to "DNS".

Closes Issue aws-controllers-k8s/community#1701
