Document that KMS encryption keys are not currently supported
Summary
There is an issue open to add support for KMS encryption for GitLab data stored in S3 buckets. Until we add support, we should document that KMS encryption is not currently supported to save GitLab users from spending time trying to configure it. A customer specifically requested that we document if after they spent time trying to get KMS encryption to work.
Proposal
Add a note in https://docs.gitlab.com/charts/advanced/external-object-storage/index.html to indicate that KMS encryption is not currently supported.
