Archive set-protocol-contracts

[rootulp]

Should we archive this repo in favor of https://github.com/SetProtocol/set-protocol-v2 ? This way future contributors won't get mixed up and accidentally create PRs against this repo (e.g. #668 , #670)

Concretely this means an admin would navigate to https://github.com/SetProtocol/set-protocol-contracts/settings and click Archive this repository
