not use default ingress controller

[lengrongfu]

If you are reporting a problem, please make sure the following information are provided:

Expected behavior and actual behavior: I created the ingress class and set it as the default ingress (kubectl annotate ingressclasses nginx ingressclass.kubernetes.io/is-default-class=true), when the ingress in the harborcluster does not set the ingressClassName, the rules cannot be created correctly in the ingress controller .

Hope that the ingress rules can be set correctly when spec.export.core.ingress.controller=default

Steps to reproduce the problem:

expose:
    core:
      ingress:
        host: core.harbor.domain
        controller: default

kubectl apply -f

Versions: Please specify the versions of following systems.

• harbor operator version: [main]
• harbor version: [2.5.2]
• kubernetes version: [1.24.0]
• Any additional relevant versions such as CertManager

this question is weird.
