fix: update collab-summit.md (nodejs#6604)

* fix: update collab-summit.md

Update the collab-summit which is now heavily out-of-date.

1. We no longer have multiple committees. There is just the TSC. Normally contributors are organized in working groups or teams.
2. Properly answer the question "who attends" to reflect reality & explain why it's attractive while also trying to make it clear that non-contributors can come too.
3. Update the repo to openjs-foundation/summits
4. Explain what actually happens in the summits these days to reflect reality.

 ## Who attends?
 
-Anyone is welcome to attend Collab Summit. During the
-summit, leaders will help onboard new contributors to groups they'd love to help
-prior to integrating them into the working sessions.
+The Collaboration Summit is primarily attended by existing contributors and
+community members, but it also welcomes those who are not yet a contributor
+and want to get onboard. If you are new to contributing to Node.js, the
+Collaboration Summit can be a good opportunity to help you learn what is
+happening within the community and contribute with the skills you have
+and would like to hone.
 
-This is your opportunity to learn what is happening within the community to jump
-in and contribute with the skills you have and would like to hone.
+Prior to the summit, contributors and community members send session proposals to
+create a schedule. Attendees can familiarize themselves with the session before
+getting onsite, having the general collaborator discussions, and then diving
+into sessions. There will also be plenty of opportunities for hallway tracks
+and brainstorms.
 
-Working groups will put together a schedule so that people can
-familiarize themselves before folks get onsite, having the general collaborator
-discussions, and then dive into breakout sessions.
