fix: Modifies install procedures

* oauthclient.yml
 * Corrects apiVersion as current causes error

* package.json
* kube-apply.sh
 * Since the patches directory has been introduced in the deploy directory,
   the kustomize install falls foul of the restricted root limit. By
   scripting the kube apply, the kustomize call can be relaxed with the
   load-restrictor switch. This is already used in the deploy directory
   Makefile
