fix(api): Fix API group mismatch between Go code and CRD

Changed API group from vnf.oran.io to mano.oran.io:
- Updated GroupVersion in vnf_types.go
- Now matches the CRD definition in config/crd/bases/mano.oran.io_vnfs.yaml
- Fixes "no matches for vnf.oran.io/v1alpha1" error in tests

This was causing VNF Controller test failures because the test environment
loaded the CRD with group mano.oran.io but the Go client was looking for
resources in vnf.oran.io group.
