Handle External API Types for Webhooks #4201
Description
What do you want to happen?
Currently, Kubebuilder has support for handling external API types when scaffolding controllers, as addressed in PR #4171. However, there is no equivalent support for webhooks when dealing with external API types.
To maintain consistency, we need to ensure that external API types are properly handled for webhooks as well, similar to how core types are managed. For reference, see the discussion around handling core types: Issue #2141.
What needs to happen:
- Add support for external API types in webhooks, similar to the approach implemented for controllers.
- Ensure that webhook scaffolding correctly identifies and handles external API types during the generation process.
Acceptance Criteria:
- External API types should be supported when scaffolding webhooks.
- Tests should cover cases where external API types are used in the webhook scaffolding process.
- We must have en example added to the testdata samples for single and multigroup layout.
