patchesStrategicMerge in kustomization.yaml has been deprecated, switch to using patches

[fortra-cloudops-platform]

Describe the bug

Kustomize has deprecated the keyword patchesStrategicMerge used in kustomization.yaml files, this feature is now supported with the patches keyword. The switch/update should be done sooner rather than later as this could start breaking those who have updated their kustomize.

To Reproduce

Build deployment manifests using a recent version of kustomize

Expected behavior
Expected not to see this when building with kustomize:

# Warning: 'patchesStrategicMerge' is deprecated. Please use 'patches' instead. Run 'kustomize edit fix' to update your Kustomization automatically.

Screenshots

If applicable, add screenshots to help explain your problem.

Version and environment information
