Bug description:
  This is the tracking bug for the .NET 8 November 2025 release.

  [Impact]

   * This corresponds to an upstream microrelease released on November 11th, 2025. See also:
     - .NET blog entry: https://devblogs.microsoft.com/dotnet/dotnet-and-dotnet-framework-november-2025-servicing-updates/
     - release announcement: https://github.com/dotnet/source-build/discussions/5414
     - .NET 8.0.22 Runtime release notes: https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.22/8.0.22.md
     - .NET 8.0.122 SDK release notes: https://github.com/dotnet/core/blob/main/release-notes/8.0/8.0.22/8.0.122.md

   * It is beneficial for all our users (including LTS users) to have
  access to the latest .NET stack.

  [Test Case]

   * The package should build successfully in -proposed (respectively).

   * The packages should be installable on jammy, noble, plucky, questing on
     amd64, arm64, s390x and ppc64el architectures.

   * Autopackage tests should pass.

  [Regression Potential]

   * The dotnet8 package has no reverse dependencies.

   * The upstream testing routine is usually satisfactory (see for
  example Microsoft's public Azure Pipeline for .NET related
  repositories: https://dev.azure.com/dnceng-public/public/_build), but
  there is always a risk of something breaking.

  [Other]

  * The tarball originated from here:
  https://github.com/canonical/dotnet-source-build-
  security/actions/runs/19172995729

  * 8.0.22 is the version number of the .NET Runtime and 8.0.122 is the version
    number of the .NET SDK.

  * We are only building the 8.0.1xx feature band, because this is the only
    feature band that allows building from source. See explanation of feature
    bands: https://learn.microsoft.com/en-us/dotnet/core/releases-and-support#feature-bands-sdk-only

  us/dotnet/core/versions/

  * PPA for review: https://launchpad.net/~mateus-
  morais/+archive/ubuntu/dotnet-november-2025-updates

  * .NET 8 on questing FTBFS on the amd64v3 architecture variant. This
  is expected and not a regression.

  * Per the .NET toolchain's policy, .NET 8 will not be included in
  resolute, therefore, there won't be a resolute build uploaded. There
  is currently a removal bug filed for dotnet8 on resolute:
