[DO NOT MERGE] Universe 2020 Day 1: December 8, 2020 (#16480)

* Update README

* [Universe] Dark mode (#16545)

* Dark mode updates (#16696)

* [Universe] Corporate sponsors (#16457)

* Dependency review beta (#16563)

* Add placeholder topic file

* Revert change I didn't make

I'm not sure where this change came from or why it's showing up in my PR here but I didn't make this change and it's not part of Dependency Review so I'm reverting it.

* Un-revert previous change

OK I see what happened there. I was comparing the PR to main rather than the Universe megabranch, hence it showed a change I didn't make.
This commit undoes the change I do not want to revert on the megabranch.
