fix: get deploy oe to run

[platocrat]

Things I did:

1. I replaced optimism-integration with optimism to build and start a local L1 and L2 instance
   2. To do this:
   3. Clone optimism repository under scaffold-eth/docker/: git clone https://github.com/ethereum-optimism/optimism.git
   4. Install and build dependencies of optimism: yarn && yarn build
   5. Build and start docker services in optimism/ops: docker-compose build && docker-compose up
2. Make sure to also clone optimism under local-optimism/docker/
3. Refactored contract calls to use gasPrice: hre.ethers.BigNumber.from('0') and gasLimit: 8999999
4. Start the scaffold-eth frontend (after installing dependencies): yarn start
5. Run yarn generate in scaffold-eth directory.
6. Fund the generated address with the local faucet at the bottom of the page.
7. Run yarn deploy-oe to see that YourCollectible token is deployed and published but ERC20, L1ERC20Gateway, and L2DepositedERC20 contracts are not.

Let me know if you have any questions my diff!
