Merge #1116: Self-host Weekly IRC meeting ical file and change meeting location from freenode -> libera.chat

820d1e8 Self-host irc meeting ical file (David Gumberg)

Pull request description:

  If it is not too inconvenient to have to make a change in this repo if/when the IRC meeting time or location changes then maybe bitcoincore.org should host and serve this file.

  I've generated a new ics file with only the currently scheduled thursday meeting time as a recurring event.
