Adds forking config to the `ethereumoptimism/hardhat` docker image. This can be configured with the following env vars: - `FORK_URL` - http provider of the remote node to fetch data from - `FORK_STARTING_BLOCK` - block to start forking from, if left undefined it will use the tip Without `FORK_URL` set, it will not run in forking mode Also adds the ability to configure the gas price with: - `GAS_PRICE` - defaults to 0, which was the previous behavior
