Support build of nupkg (equivalent of dotnet pack command)

We have a need to build a nupkg from a dotnet_library. Is there a way in rules_dotnet or using a genrule on rules_dotnet outputs to do this?

If not, could this be supported?

I understand this is the equivalent of the 'dotnet pack' command.

Start by examining the repository's dotnet_library outputs and whether a genrule can invoke the dotnet pack equivalent described in the issue. Done means defining support that produces a nupkg from a dotnet_library; the issue names no files or tests, so the relevant entry points and validation coverage must first be located.
