The only thing that differs is the paths to the contracts

Move the `contracts` directory to `src` and then move
the tests into a top level `test` dir so that its
standard foundry style for a repo.

This is going to break any in flight PRs so worth trying
to get in relatively quickly, will be no fun to rebase a
bunch of PRs.

Will need to follow up with another commit that bumps the
patch versions.

devnet: allow unprotected txs

feat(op-chain-ops): WithdrawalNetwork Type

op-e2e: make TestBatcherMultiTx more resilient

txmgr: Increase default network timeout to 10s

contracts-bedrock: delete dead deploy config

op-node: safer genesis script

feat: gitmodules for contracts deps

feat(ctb): Semver lockfile

goerli-forked is no longer used, it can be safely deleted from the
repository.

Updates the `op-node` genesis gen script to prevent `nil` pointer
access accidentally. Run the command like so:

```go
go run op-node/cmd/main.go genesis l2 \
  --deploy-config $PWD/packages/contracts-bedrock/deploy-config/mainnet.json \
  --outfile.l2 l2.json \
  --outfile.rollup rollup.json \
  --l1-rpc $ETH_RPC_URL \
  --deployment-dir $PWD/packages/contracts-bedrock/deployments/mainnet
```

When generating the genesis file, it is ok to leave the
`l1StartingBlockTag` value as undefined, this script will select an
appropriate value and then the value will end up inside of the rollup
config under `.genesis.l1.hash` which can then be backported to
the deploy config to make the script deterministic.
