Descriptor types missing network-status-microdesc-consensus-3

Hi Karsten. While looking over stem's code I just realized that the @type annotation for "network-status-microdesc-consensus-3" isn't on...

https://metrics.torproject.org/formats.html#descriptortypes

This comes from one of Ravi's commits...

https://gitweb.torproject.org/stem.git/commit/8ad310114b1ea7b743a868a8b70832eea5b8f3e2

... so I'm not positive where it came from, but should that @type annotation be on the page?

Thanks! -Damian
