Please merge os-prober 1.81 (main) from Debian unstable (main)

Version 1.81 brings support for Windows 11 boot partitions.
In Ubuntu, when the variable WINOSDATA is set, we attempt to detect the Windows data partitions.

Windows 10 and Windows 11 have the same major version number. The "standard" way to make the distinction seems to be to compare the Windows build number:

major = 10, build number >= 22000 <- Windows 11
major = 10, build number < 22000 <- Windows 10

Unfortunately, the build number is not easily accessible. It is available in the HKLM/Software registry hive (i.e., Windows/System32/config/SOFTWARE).
Parsing this binary file properly would require adding a new dependency to os-prober. Multiple packages in the archive are able to parse this type of file, including libhivex-bin, but none of them are in main.

$ hivexget SOFTWARE 'Microsoft\Windows NT\CurrentVersion' | grep CurrentBuildNumber
"CurrentBuildNumber"="19044"

For now, I have added a FIXME to mention that we make no distinction between Windows 11 and Windows 10.

Adding debdiff from the old Ubuntu release

Adding debdiff from the Debian release.

Successful build on PPA: https://launchpad.net/~ogayot/+archive/ubuntu/kinetic-proposed/+build/24307846

Note about the following dropped change:

    - Sort detected kernels by modification time, if possible.

The new version sorts the kernels by reverse natural number order ; instead of modification time.
There is no guarantee that the order will be preserved after upgrading os-prober. However, tor the most common scenarios, it should have no impact. I tested with the data from the original LP bug: https://bugs.launchpad.net/ubuntu/+source/os-prober/+bug/1317153 and the kernels are listed in the expected order.

Relying on the name of the file (and therefore parsing the version number) feels more solid than relying on the modification time.

thanks, LGTM. I've only added a reference to this LP bug into your FIXME comment, to provide more context for future readers.

This bug was fixed in the package os-prober - 1.81ubuntu1

---------------
os-prober (1.81ubuntu1) kinetic; urgency=low

  * Merge from Debian unstable (LP: #1987386). Remaining changes:
    - Mount btrfs subvolume @ when present to access a btrfs formatted
      rootfs.
    - When called with WINOSDATA, return the list of Windows partitions
      containing the system instead of only listing these containing the
      bootrecord. Add Windows10 detection.
    - Stop building the udeb on request.
  * Dropped changes, superseded in Debian:
    - Sort detected kernels by modification time, if possible.
      => Kernels are now sorted by - reverse - natural number order (see
         option -v of ls).
  * Added FIXME tag mentioning that Windows 11 system partitions are detected
    as Windows 10 when os-prober is called with WINOSDATA
