Fixup examples in README.md

* Conformitron uses AWS Secret Store, and most of the README refers to
  Secret Store, but the local testing ClusterSecretStores example in the
  README used Parameter Store instead. This could cause confusion for
  people not familiar with setting up External Secrets. Fix is to
  specify SecretStore in the example.

* The Flux Kustomization directions for local testing used the same
  kustomization name for the addon definition and also for its test.
  This is likely to cause Flux to replace the existing kustomization
  with the test path, deleting the addon resources themselves. Fix is to
  use a different name for the testing kustomization.
