Can you please cleanup the { if release candidate } Documentation: https://development.agones.dev/site/ in https://agones.dev/site/blog/2022/02/15/1.21.0-lots-of-bug-fixes/ as well?

Just checking the release checklist - I don't expect it will make a change, but just wanted to double check that you ran make gen-install gen-api-docs, since it wasn't ticked off.
