🌱 bump the k8s-dependencies group with 9 updates - #3958
This is an additional minor release independent of the Kubernetes release cadence to deliver
kubernetes-sigs/controller-tools#1474 because this bug fix is a breaking change so it was not possible to backport it.
Dependabot will resolve any conflicts with this PR as long as you don't alter it yourself. You can also trigger a rebase manually by commenting @dependabot rebase.

Details
Needs approval from an approver in each of these files:
I'm waiting for a operator-framework 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.
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.
The PR updates Kubernetes dependencies from v0.37.1 to v0.37.2 and controller-tools from v0.22.0 to v0.23.0. Vendored changes update HTTP server setup, CRD schema and validation generation, generator options, and help output.

Summary
Dependency version alignment go.mod, vendor/modules.txt
Kubernetes modules move to v0.37.2, and controller-tools moves to v0.23.0.
HTTP server header-value limit vendor/k8s.io/apiserver/pkg/server/*serving.go, vendor/k8s.io/apiserver/pkg/server/header_value_count_*.go
Secure and deprecated insecure serving apply a Go-version-specific header-value-count setting before starting the server. The Go 1.27 implementation sets the limit to 16384; earlier Go versions use a no-op.
CRD schema and validation generation vendor/sigs.k8s.io/controller-tools/pkg/crd/flatten.go, vendor/sigs.k8s.io/controller-tools/pkg/crd/schema.go, vendor/sigs.k8s.io/controller-tools/pkg/crd/markers/*
Schema generation adds array and object types to named slice and map references. Validation marker parsing adds k8s:maxItems, k8s:minimum, and k8s:maximum; k8s:required applies minimum constraints when they are not already set. Conflict handling also covers XListType and XListMapKeys.
Generator options and help output vendor/sigs.k8s.io/controller-tools/pkg/applyconfiguration/*, vendor/sigs.k8s.io/controller-tools/pkg/crd/gen.go, vendor/sigs.k8s.io/controller-tools/pkg/crd/zz_generated.markerhelp.go, vendor/sigs.k8s.io/controller-tools/pkg/genall/help/pretty/print.go, vendor/sigs.k8s.io/controller-tools/cmd/controller-gen/main.go
Apply-configuration and CRD generators add OmitToolVersion to normalize the generated header name or omit the version annotation. The pretty-print Span interface and implementations rename WriteTo to Write; controller-gen help output uses the renamed method.
This dependency bump updates Kubernetes modules to v0.37.2 and controller-tools to v0.23.0. The vendored generator has an upstream edge-case defect with named byte-slice types. This repository has no such CRD input and does not run controller-gen on its API types, so the bump is safe to merge with owner awareness.

363-364: Trivial · Data Integrity & Integration · Poor tradeoff
Preserve the serialized type of named slice references.
For type Blob []byte, localNamedToSchema and namedToSchema assign "array" to the field reference, while the referenced definition is "string" with format "byte". Flattening retains both schemas in allOf, and conflict handling records a type conflict that can fail CRD generation.
Use the generated schema type for named slice references, or special-case serialized types such as byte slices instead of deriving the type only from the Go underlying type. This is a latent controller-tools defect; the current repository has no matching CRD input.

Update the *types.Slice handling used by localNamedToSchema and namedToSchema so
named slice references retain the generated schema’s serialized type instead of
always setting props.Type to arrayType; preserve byte slices as string with
format byte and ordinary slices as arrays.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Resolve the referenced type before applying the required-field bound.
If a +k8s:required field uses an external named string type, namedToSchema leaves the field schema’s Type empty and sets Ref. This branch assigns MinProperties: 1, which constrains objects, not strings. The generated schema therefore does not enforce the documented non-empty string requirement. Apply the bound for the referenced schema’s actual serialized type. (raw.githubusercontent.com)
