chore(deps): Update controller-runtime from v0.23.3 to v0.24.0 and k8s dependencie to support k8s 1.36

[dongjiang1989]

Description

Upgrade controller-runtime from v0.23.3 to v0.24.0 and k8s dependencies to support k8s 1.26

Changes required:

⚠️ controller-runtime v0.24.0 deprecated scheme.Builder:

// Deprecated: This helper is only useful in api packages, but api packages                     
// should be easy to import and hence have minimal dependencies.                                
type Builder struct { ... }                                                                     

Solution

Replace deprecated sigs.k8s.io/controller-runtime/pkg/scheme.Builder with
k8s.io/apimachinery/pkg/runtime.NewSchemeBuilder() in scaffolding templates.

Before:

import "sigs.k8s.io/controller-runtime/pkg/scheme"
SchemeBuilder = &scheme.Builder{GroupVersion: SchemeGroupVersion}

After:

import "k8s.io/apimachinery/pkg/runtime"                                                        
SchemeBuilder = runtime.NewSchemeBuilder(func(scheme *runtime.Scheme) error {                   
   metav1.AddToGroupVersion(scheme, SchemeGroupVersion)                     
   return nil                                                                                  
})            

This reduces API package dependencies and follows Kubernetes core API patterns.

Pull request overview

This PR upgrades Kubernetes/controller-runtime Go dependencies and updates the API scaffolding to remove usage of the deprecated sigs.k8s.io/controller-runtime/pkg/scheme.Builder, aligning the API packages with the upstream Kubernetes runtime.SchemeBuilder pattern. It also regenerates CRD manifests/templates to reflect the updated dependency schema metadata.

Changes:

• Bump sigs.k8s.io/controller-runtime to v0.24.0 and update k8s.io/* module versions accordingly (plus related dependency refresh in go.sum).
• Replace deprecated controller-runtime scheme.Builder usage with k8s.io/apimachinery/pkg/runtime.NewSchemeBuilder and update type registration to AddKnownTypes(...).
• Regenerate CRD YAMLs (both go/api/config/crd/bases and Helm CRD templates), updating description text based on the newer schema source.
