The package in question is this one:
Microsoft.VisualStudio.CodingConventions

I was looking into creating a new pipe for a GTK3 upgrade, when I noticed all pipes were failing
because nuget couldn't find a specific version of that package. I'm not sure why, I can't find it anywhere
either. but locally it seemed that nuget has an older version available: 1.1.20180503.2
Ideally, this old package should be factored out and replaced by something newer, so maybe it's smth
to put on the roadmap.
