Rename EncryptionConfig to EncryptionConfiguration (#11080)

EncryptionConfig was renamed to EncryptedConfiguration and added to
the `apiserver.config.k8s.io` API group in Kubernetes 1.13.

The feature was previously in alpha and was not handling versions
properly, which lead to an originally unnoticed `v1` in the docs.
