Change CredentialProviderConfig API version to v1beta1

[stmcginnis]

Issue number:

Closes #2905

Description of changes:

API version was set to v1 for Kubernetes 1.25, but that version is not available until Kubernetes 1.26. This fixes the version specifier to v1beta1 to match the correct version for this release.

Testing done:

Visual verification, and confirmed API version for 1.25 with https://kubernetes.io/docs/reference/config-api/kubelet-credentialprovider.v1beta1/

Deployed node with changes. Configured credential provider with:

# apiclient apply << EOF
> [settings.kubernetes.credential-providers.ecr-credential-provider]
> enabled = true
> # (optional - defaults to "12h")
> cache-duration = "30m"
> image-patterns = [
>   # One or more URL paths to match an image prefix. Supports globbing of subdomains.
>   "*.dkr.ecr.us-east-2.amazonaws.com"
> ]
> EOF

Verified settings:

# cat /etc/kubernetes/kubelet/credential-provider-config.yaml
apiVersion: kubelet.config.k8s.io/v1beta1
kind: CredentialProviderConfig
providers:
  - name: ecr-credential-provider
    matchImages:
      - "*.dkr.ecr.us-east-2.amazonaws.com"
    defaultCacheDuration: "12h"
    apiVersion: credentialprovider.kubelet.k8s.io/v1beta1
    env:
      - name: HOME
        value: /root

Rebooted with apiclient reboot and waited for node to come back up.

Verified kubelet was happy:

# systemctl status kubelet
