📖 Addressing Deprecated Manager Options

[buraksekili]

Description

This PR proposes an update to the documentation available at https://book.kubebuilder.io/cronjob-tutorial/empty-main.html#every-journey-needs-a-start-every-program-needs-a-main. The reason for this revision is that the current documentation still references deprecated cache settings, such as cache.MultiNamespacedCacheBuilder.

Motivation

With the release of controller-runtime v0.15.0, several Manager Options have undergone refactoring and deprecation. As a result, the documentation needs an update since it still refers to old Manager Options.

Hi @buraksekili. Thanks for your PR.

I'm waiting for a kubernetes-sigs member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Instructions for interacting with me using PR comments are available here. If you have questions or suggestions related to my behavior, please file an issue against the kubernetes/test-infra repository.
