[SRU] New upstream microrelease .NET 6.0.29 and SDK 6.0.129

[Dominik Viererbe]

[Impact]

 * This correspond to an upcoming upstream microrelease (Microsoft Patch Tuesday microrelease).

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

 * This update is bundled with minor fixes:
   - updates Canonical support information
   - fixes/adds version parsing edge cases

[Test Case]

 * The package should build successfully in mantic-proposed and jammy-proposed.

 * The packages should be installable on mantic and jammy
   on amd64 and arm64 architectures.

 * Autopackage tests should pass.

 * The usual manual tests that have been seen in the previous microreleases
   LP: #2057699, #1996499, #1983380, #2011807 (see Test Case section there).

   Note: The need for manual testing is largely reduced since the last SRU,
         because the autopkgtests improvements far exceeds the coverage
         provided by the mentioned manual test plans.

[Regression Potential]

 * Upstream tests are usually satisfactory, but there is always a risk of something breaking.

[Other]

* dotnet6 was removed from the current development release.
  See LP: #2044511 for details.

* 6.0.29 is the version number of the .NET Runtime and 6.0.129 is the version
  number of the .NET SDK. The package version only refers to the SDK version
  number.

* We are only building the 6.0.1xx feature band, because this is the only
  feature band that allows to be build from source. See explanation of feature
  bands: https://learn.microsoft.com/en-us/dotnet/core/releases-and-support#feature-bands-sdk-only
