When migrating the `pod-secrets` Secret to a SealedSecret, I
accidentally created it using the `--from-file` instead of
`--from-env-file` argument to `kubectl secret create generic`. This had
the effect of creating a single key named `pod.secrets` with the entire
contents of the file as its value. This broke backups to MinIO, since
the PostgreSQL containers could no longer read the credentials from the
environment. Regenerating the SealedSecret with the correct arguments
resolves this issue.
