Web hook to add new contracts deployed by projects already in the registry

[ccerv1]

Lot of people use hardhat deployer or foundry scripts to deploy. It will be cool to build a hook that automatically adds contract address to the repo or creates a PR. Or even better, writes to chain and you can read from there.

Proposal

1. Get the origin git remote and the commit hash
2. Get the contract address that we just deployed
3. Mint an EAS attestation using the same wallet that pairs these 2 things
