[SRU] New upstream microrelease .NET 7.0.18 and SDK 7.0.118

[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: #2057982, #2011809, #2024893, #2009855, #2003691, #2011675 (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]

* dotnet7 was removed from the current development release.
  See LP: #2044513 for details.

* 7.0.18 is the version number of the .NET Runtime and 7.0.118 is the version
  number of the .NET SDK. The package version only refers to the SDK version
  number.

* We are only building the 7.0.1xx 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

Hello Timo (or someone else from the SRU Team), the dotnet7 (and also dotnet6) package is known to contain a .git directory. I should have put this in the SRU description. The build process gathers metadata that is required. Upstream fixed this with dotnet8. We do not want to spend time on backporting this, because .NET 7 will go EoL (upstream) in less than a month (on 14th May 2024).

accepted from the rejected queue, so this bug didn't get spammed
