- Added new feature gate called `RuntimeClassInImageCriApi` to address `kubelet` changes needed for KEP 4216.
  Noteable changes:
  1. Populate new `RuntimeHandler` field in CRI's `ImageSpec` struct during image pulls from container runtimes.

  with the number of existing entries in the internal cache
  
  - `rest_client_transport_create_calls_total` is a counter
  that increments each time a new transport is created, storing
  the result of the operation needed to generate it: hit, miss
  or uncacheable. ([#117295](https://github.com/kubernetes/kubernetes/pull/117295), [@aojea](https://github.com/aojea))

Kubernetes releases are now generating provenance attestation files describing the staging and release phases of the release process and artifacts are verified as they are handed over from one phase to the next.
This final piece completes the work needed to comply with Level 1 of the [SLSA security framework](https://slsa.dev/) (Supply-chain Levels for Software Artifacts).

* With this PR, kubectl and other RestClient's using the AuthProvider framework can make OIDC authenticated requests, and, if there is a refresh token present, the tokens will be refreshed as needed.

- Removed the `UserNamespacesPodSecurityStandards` feature gate. The minimum supported Kubernetes version for `kubelet` is now `v1.31`, so the gate is no longer needed.

- Promoted `StatefulSetStartOrdinal` to stable. This means `--feature-gates=StatefulSetStartOrdinal=true` are not needed on kube-apiserver and kube-controller-manager binaries and they'll be removed soon following policy at https://kubernetes.io/docs/reference/using-api/deprecation-policy/#deprecation.
