minio: Install and configure MinIO

[MinIO][0] is an S3-compatible object storage server.  It is designed to
provide storage for cloud-native applications for on-premises
deployments.

MinIO has not been packaged for Fedora (yet?).  As such, the best way to
deploy it is usining its official container image.  Here, we are using
`podman-systemd-generator` (Quadlet) to generate a systemd service
unit to manage the container process.
