Broken GitHub links for olymsig repositories in README (404 errors)

[brunacunha]

These links in the README return 404 errors: People outside of the team probably don't have permission to see it.

• https://github.com/OlympusDAO/olymsig
• https://github.com/OlympusDAO/olymsig-testnet

Line on README: "the olymsig repos: mainnet and testnet"

Would it be possible to update or remove these links?

Thanks for maintaining the project!
