Add kubebuilder markers for resource path and shortname

[shubham-pampattiwar]

This PR adds kubebuilder markers to support Non-Admin backups CR's short name.

What this means ?
Earlier to fetch non-admin backups CRs you would execute the command
oc get nonadminbackups
After this PR, you could use the shortname nab instead of the fullname nonadminbackups

How to test ?

• Install the non-admin backup CRD from this PR
• Try to execute CRUD commands on nonadminbackups CRD/API endpoint using nab shortname instead of full name nonadminbackups
  for example:
  oc get nab
