api-approved.kubernetes.io missing from CRD since 0.14.2

[morremeyer]

What happened: 4e6dd80 removed the api-approved.kubernetes.io annotation which is required.

What you expected to happen: The annotation to not be removed. It is required as explained in #2008 and initially added in #2007.

How to reproduce it (as minimally and precisely as possible): Try to kubectl apply -f https://raw.githubusercontent.com/kubernetes-sigs/external-dns/v0.14.2/docs/contributing/crd-source/crd-manifest.yaml and observe the error:

Required value: protected groups must have approval annotation "api-approved.kubernetes.io", see https://github.com/kubernetes/enhancements/pull/1111

This can also be seen in https://github.com/community-tooling/charts/actions/runs/9149321522/job/25152820816?pr=277

Anything else we need to know?:

Environment:

• External-DNS version (use external-dns --version): 0.14.2
• DNS provider: irrelevant
