Prep the repo to switch deployment to Vercel

[ken-futureverse]

• Remove all stale branches (please consult with @KarishmaBothara first)
• Rename develop to main
• Create a new prod from develop, making sure it doesn't contain unreleased commits
• Setup project on Vercel and make sure they are built correctly
• Make sure the production branch is set to prod (ask Marco to change)
• Setup domains to have cennznet.io to be the Production, (do not change DNS record until we are happy with it)
