Merge #12997: [doc] build-windows: Switch to Artful, since Zesty is EOL

fad2958 [doc] build-windows: Switch to Artful, since Zesty is EOL (MarcoFalke)

Pull request description:

  According to https://wiki.ubuntu.com/Releases#End_of_Life, Zesty is EOL, so bump to Artful for now.

  Note that Artful is going to be EOL soon as well, so I am not sure how to proceed after that.
