This release of MinIO migrates the chart to the passthrough pattern.

Values overrides are now nested under the upstream key. For example:

mimir:
  values:
    minio-tenant:
      tenant:
        pools:
        - name: pool-0
          servers: 3
          volumesPerServer: 4

becomes:

mimir:
  values:
    minio-tenant:
      upstream:
        tenant:
          pools:
          - name: pool-0
            servers: 3
            volumesPerServer: 4
