I tried using pulumi kubernete custom resource, but i got the following error, anyone know how i can force using 'v1' instead of 'v1beta1'?

const trailingSlashMiddleware = new k8s.apiextensions.CustomResource(`${name}-trailing-slash`, {
      apiVersion: '<http://traefik.containo.us/v1alpha1|traefik.containo.us/v1alpha1>',
      kind: 'Middleware',
      metadata: { namespace: args.namespace },
      spec: {
        redirectRegex: {
          regex: `^.*\\${args.prefix}$`,
          replacement: `${args.prefix}/`,
          permanent: false,
        },
      }, 
    }, { provider: opts?.provider });

-----------ERROR----------

you’re going to have to update traefik to get the v1 custom resource definitions
