Bug description:
  [Impact]
  parted reports NVMe devices as "Unknown", which propagates up to d-i:

    ┌────────────────────────┤ [!!] Partition disks ├─────────────────────────┐
    │ │
    │ Note that all data on the disk you select will be erased, but not │
    │ before you have confirmed that you really want to make the changes. │
    │ │
    │ Select disk to partition: │
    │ │
    │ /dev/nvme0n1 - 450.1 GB Unknown │
    │ SCSI1 (0,0,0) (sdi) - 240.1 GB ATA INTEL SSDSC2BB24 │
    │ SCSI3 (0,0,0) (sdj) - 800.2 GB ATA SDLFOCAM-800G-1H │
    │ │
    │ <Go Back> │
    │ │
    └─────────────────────────────────────────────────────────────────────────┘

  While d-i works fine with this device as-is, the "Unknown" string is a
  source of consternation with some users who aren't sure if NVMe is
  supported.

  [Test Case]
  Current:
  $ sudo parted -s /dev/nvme0n1 p
  Model: Unknown
  Disk /dev/nvme0n1: 512GB
  [...]

  Expected:
  $ sudo parted -s /dev/nvme0n1 p
  Model: NVMe Device (nvme)
  Disk /dev/nvme0n1: 512GB
  [...]

  [Regression Risk]
  There maybe user code out there relying on the existing "Unknown" output.
