Supersedes https://github.com/void-linux/void-packages/pull/27170. I followed the [packaging guidelines](https://github.com/dotnet/source-build/blob/v5.0.206.1-SDK/Documentation/packaging-installation.md) in the source-build repo. I aligned with the [recommended packages list here](https://docs.microsoft.com/en-us/dotnet/core/distribution-packaging) minus `dotnet-runtime-deps`.
