fix(deploy): do not bind webhook port 10260 (#495)

Our dependency `k/cloud-provider` started binding this port in version
0.27.0 to serve webhooks from. We are not using the webhook feature and
the port bind is causing conflicts for deployments that use the native
networking feature (which enables `hostNetwork`).
