fresh build find no config

[NOOMA-42]

Describe the bug
this happens in post-relay branch and branch rebased on it.
yarn deploy generates config.ts in root folder, but to build this branch current commit requires this config.ts which doesn't exist if you didn't run yarn deploy

To Reproduce
fresh clone test/post-relay branch and build

Expected behavior
For information, contracts package.json

"scripts": {
    "build": "yarn buildVerifier && hardhat compile && yarn abi",
    "buildVerifier": "ts-node ./scripts/genVerifier.ts ",
    "abi": "ts-node scripts/abi",
    "hardhat": "hardhat",
    "deploy": "hardhat run scripts/deploy.ts",

yarn deploy generates config.ts in root folder, but to build this branch current commit requires this config.ts which doesn't exist if you didn't run yarn deploy
