Delete/Archive collaboration repo

[williamkapke]

I think the spirit of this effort is now taken over by the Community Committee. Every little bit of cleanup helps new folks.

Might want to archive the inclusivity repo too for the same reason. Might also be worthwhile either removing or updating the membership for the @ nodejs/collaboration and @ nodejs/inclusivity teams too. (The collaboration one especially, as it is often what comes up when one is trying to @-mention nodejs/collaborators instead.)

Lets hold off inclusivity for now...it's possible it will be reused. More info: nodejs/community-committee#13.

+1 on archiving this repo.

Let's not get into the habit of deleting any repos. Let's mark it archived and just let it be.

I have updated the collaboration repo to mark it inactive
