Fixup kustomize fields

[kubasikus]

ArgoCD sync is failing due to incorrect field naming. Fixes done by running "kustomize edit fix" in the dev/ and prod/ dirs

@devopsjourney1 Hey there, the kustomized webapp sync isn't working due to problems with the kustomize files. This is affecting people following your tutorial. I've tested that with these changes, things work well again.

I encountered this error while using your code, it is not working:

Unable to create application: application spec for kustom-app-dev is invalid: InvalidSpecError: Unable to generate manifests in kustom-webapp/overlays/dev: rpc error: code = Unknown desc = `kustomize build <path to cached source>/kustom-webapp/overlays/dev` failed exit status 1: # Warning: 'patchesStrategicMerge' is deprecated. Please use 'patches' instead. Run 'kustomize edit fix' to update your Kustomization automatically. # Warning: 'commonLabels' is deprecated. Please use 'labels' instead. Run 'kustomize edit fix' to update your Kustomization automatically. Error: no matches for Id Deployment.v1.apps/mywebapp-dev.[noNs]; failed to find unique target for patch Deployment.v1.apps/mywebapp-dev.[noNs]

I am not sure why 'patchesStrategicMerge' is deprecated, this thing is so stupid and confusing.
