[OSPRH-19301] Remove deprecated Kustomize fields in config dir

Update all deprecated Kustomize fields to their modern equivalents across
the config directory to ensure compatibility with Kustomize v5.3+ and
future versions.

Changes made:

config/default/kustomization.yaml:
- Replace 'bases:' with 'resources:'
- Replace 'patchesStrategicMerge:' with 'patches:'
- Convert patch entries to use 'path:' format

config/crd/kustomization.yaml:
- Replace 'patchesStrategicMerge:' with 'patches:'
- Update commented patch entries to use 'path:' format for both
  webhook and cainjection patches

config/manifests/kustomization.yaml:
- Replace commented '#patchesJson6902:' with '#patches:'

config/scorecard/kustomization.yaml:
- Replace 'patchesJson6902:' with 'patches:'
- Update kubebuilder scaffold comment from 'patchesJson6902' to 'patches'

These changes eliminate deprecation warnings and align with the modern
Kustomize field syntax while maintaining full backward compatibility.
The modernization follows patterns established by other OpenStack K8s
operators and industry best practices.
