swap SE-2 w/ hardhat for SE-2 w/ foundry

[MattPereira]

Summary

• deleted everything on main branch except the README that is specific to defi challenges repo
• used npx create-eth@latest command and selected foundry option

Local Testing

1. run yarn to install dependencies
2. run yarn chain to spin up local network
3. run yarn start to see frontend at localhost:3000
4. run yarn deploy to deploy contracts on local foundry network

TODO

• Fix CI lint check that is failing
  • gh-actions fails for foundry scaffold-eth-2#607

Looks good to me, except we need to resolve the failing checks.

As discussed on our call, this looks good. We are troubleshooting why the linter is failing but that might be more of a Scaffold-ETH problem with their workflow file.

The failing CI is something that Shiv Bhonde has brought up to us. It is being discussed in this issue I believe. So we can move ahead and have this merged to main and git pull SE-2 into the other challenge branches, and future branches onward!

Great job again :)
