Replace jekyll doc generation with .NET-based generator

Would be nice to finish removing the Ruby dependency from the builds.

Just one more option: there's pretzel that's close to Jekyll and "should be compatible with basic Jekyll websites." https://github.com/Code52/pretzel

An option from MS https://github.com/dotnet/docfx

@dtchepak I don't think we have plans for this right? Should we close this issue then?

@304NotModified https://github.com/dotnet/docfx that @alexandrnikitin suggested still looks like a good option. I would still like to simplify builds by not having to rely on ruby. 🤔

I'll tags as help-wanted and hope for the best 😂
