Enable kube-api-linter module in golangci-lint

[moko-poi]

Enable kube-api-linter module in golangci-lint to enforce Kubernetes API conventions and best practices.

Motivation

The kube-api-linter is an official linter from kubernetes-sigs that checks Kubernetes API types for common mistakes and enforces best practices based on the Kubernetes API
Conventions.

Currently, this project uses golangci-lint v2.4.0 but only has the default linters enabled (errcheck, govet, ineffassign, staticcheck, unused).

Proposed Changes

1. Create .custom-gcl.yml to configure the kube-api-linter module:

version: v2.5.0
name: golangci-lint-kube-api-linter
destination: ./bin
plugins:
  - module: 'sigs.k8s.io/kube-api-linter'
    version: 'v0.0.0-20251029102002-9992248f8813'

2. Create .golangci.yml to enable the linter:

linters-settings:
  custom:
    kubeapilinter:
      type: "module"
      description: "Kube API Linter lints Kube like APIs based on API conventions and best practices"

linters:
  enable:
    - kubeapilinter

3. Update CI workflow if necessary

Hi @moko-poi,
Thank you as always!

I'm afraid I don't have free capacity to process your PR within this release cycle (1.2.0) for sure. Too many internal tasks and holidays. Hope you're OK with waiting for PR feedback until 1.3.0, and LMK if not! Meanwhile, please see that CI for the PR fails:

Also, could you please elaborate what worries exactly you wish to address with the kube-api-linter. Like, is there anything specific that causes friction?
