Remove outdated patch versions
- Remove dotnet 1.1.6, 2.1.103
- Remove dotnet-framework 1.0.8, 2.0.0

We removed frameworks that don't have a matching dotnet SDK. We removed dotnet SDKs that we no longer support, due to the two-per-minor-line policy.
We ensured that all dotnet-frameworks for a each dotnet version are in the manifest.
