feat: Update CronJob and Multiversion tutorials to use Status Conditions

[nerdeveloper]

• Add Status Conditions support following K8s API conventions
• Implement meta.SetStatusCondition() throughout reconciliation
• Add condition types: Available, Progressing, Degraded
• Update tests to verify Status Conditions behavior
• Add test cases for suspended CronJobs

This aligns the tutorials with best practices demonstrated in the Deploy Image Plugin example, addressing issue #5024 and #4019.

Note: This PR contains manual changes to the tutorial code. The CI will fail as make generate needs updates (will be handled in a follow-up PR per the proposed solution).

Hi @nerdeveloper. 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-sigs/prow repository.
