deprecated kubernetes-external-secrets replaced by operator

[rjminsha]

https://cloud.ibm.com/docs/secrets-manager?topic=secrets-manager-tutorial-kubernetes-secrets documentation points user to install from https://github.com/external-secrets/kubernetes-external-secrets which is deprecated.

This project has been [deprecated](https://github.com/external-secrets/kubernetes-external-secrets/issues/864). Please take a look at ESO (External Secrets Operator) instead https://github.com/external-secrets/external-secrets

Docs perhaps should be updated with install directions using operator

Hi @rjminsha, sorry for the late reply on this!

We're working on updating our docs to update the install instructions using External Secrets Operator -- will post here after the changes are complete. Thank you!
