CBL Mariner 2.0 is EOL and will not receive any more updates. This PR removes all CBL Mariner 2.0 images.

A few things were left in place for compatibility:

  • dotnet/monitor and dotnet/monitor/base 8.1 images have undocumented cbl-mariner-distroless shared tags which redirect to azurelinux-distroless. This was intentional, for context: Update .NET Monitor 8 CBL-Mariner images to Azure Linux 3.0 #6257
  • There are tests that ensure these tags exist. So all of the test infrastructure that knows about and tests for these Mariner tags also has to stay around.
