Updating meeting details

I was struggling to find the right meeting, I eventually found it at the big [kubernetes calendar](https://calendar.google.com/calendar/u/0/[email protected])
after mbbroberg gave me the time for it.  This update should make it easier to find.

I believe the meetings link should have been to the `#contributor-comms` anchor, so I updated that too, let me know if I'm wrong.
