Replace MinIO server in tests #729
Description
MinIO is mostly dead these days (it has been replaced with a proprietary offer). The tests still run against a rather old version from August 2020. It would make sense to test against something else that is S3-compatible and also maintained.
I looked into RustFS a while back, but it seemed a little odd to me. Other options would be Garage or a shim layer like Versity.
