fix: add kubebuilder markers for non-breaking kube-api-linter issues

[moko-poi]

#2419

Summary

This PR addresses non-breaking kube-api-linter issues identified in #2618 by adding appropriate kubebuilder markers to API field definitions.

Changes

Added kubebuilder markers:

• List fields: Added +listType=atomic to Taints, StartupTaints, Requirements, and Budgets
• List fields: Added +listType=set to Reasons (no duplicates allowed)
• List fields: Added +listType=map with +listMapKey=type to Conditions (indexed by type)
• Map fields: Added +mapType=atomic to Labels
• Map fields: Added +mapType=granular to Annotations

Retained //nolint:kubeapilinter for:

• Embedded fields (metav1.ObjectMeta, Status, etc.)
• Pointer types (*NodeClassReference, *metav1.Duration, etc.)
• Primitive fields in Status structs
• Fields with design constraints requiring breaking changes

Testing

All changes are non-breaking and only add metadata markers that don't affect runtime behavior or API compatibility.

Hi @moko-poi. Thanks for your PR.

I'm waiting for a github.com 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.
