[TUTORIAL] Improve L2 Testnet Tutorial

[sbvegan]

Brief Description of the Docs Request

The, "Creating Your Own L2 Rollup Testnet" tutorial is currently pinned at an older branch so the tutorial doesn't break with the latest changes to develop. We should update it to be more recent.

Description of the Documentation You'd Like

Two approaches:

1. Update the tutorials/chain in the monorepo, verify the tutorial works as expected
2. Update the tutorial to be more evergreen. Explain that you need to deploy the contracts from op-contracts-vX.X.X, and run the client software from a different branch. Also check that the genesis and rollup config generation is solid.

Someone also says op-contracts/v1.3.0 branch can't deploy

ethereum-optimism/developers#344

It still fail after switch to op-contracts/v1.3.0. cause of failure seems to be latest release of foundry.
set specific version when install foundry. below is example

Hey, I solved this problem by following their suggestions. OP has made changes in the codebase to generate the genesis and rollup. You may want to follow the discussion below to make it work. Two highlights: 1. uses https://github.com/ethereum-optimism/optimism/tree/op-contracts/v1.3.0 to deploy v1 contract 2.write your l1-deployment json file like https://github.com/ethereum-optimism/superchain-registry/blob/main/superchain/extra/addresses/sepolia/base.json

Branch op-contracts/v1.3.0 and beyond doesn't have sync() anymore but the document is still using sync()

[opfocus]

In the "Creating Your Own L2 Rollup Testnet" tutorial, two issues are currently being faced:

• The forge script scripts/Deploy.s.sol:Deploy --sig 'sync()' --rpc-url $L1_RPC_URL in the tutorial is no longer applicable when users create using the release branch instead of the tutorials/chains branch.
  [OP Stack Deployment] basic install developers#110

• Even when following the steps in the tutorials/chains branch, users are still encountering issues.

it seems that all the issues point towards the process involving the forge script scripts/Deploy.s.sol:Deploy --sig 'sync()' --rpc-url $L1_RPC_URL.

When I deployed the op according to the tutorial, i ran into three new issues:

1. executing forge script scripts/Deploy.s.sol:Deploy --private-key $GS_ADMIN_PRIVATE_KEY --broadcast --rpc-url $L1_RPC_URL --slow to deploy the contract to L1, it comes up:

Error: 
Failed to send transaction

Context:
- server returned an error response: error code -32000: max priority fee per gas higher than max fee per gas

solution:
remove --slow flag and add --with-gas-price <value> flag, such as --with-gas-price 2gwei.

2. Newer versions dont rely on the artifacts. So create genesis files command should be changed to:

go run cmd/main.go genesis l2 \
  --deploy-config ../packages/contracts-bedrock/deploy-config/getting-started.json \
  --l1-deployments ../packages/contracts-bedrock/deployments/getting-started/.deploy \
  --outfile.l2 genesis.json \
  --outfile.rollup rollup.json \
  --l1-rpc $L1_RPC_URL

3. since artifacts have been remove, so some of the artifact-dependent commands should be modified and described accordingly, for example op-proposer start command:

./bin/op-proposer \
  --poll-interval=12s \
  --rpc.port=8560 \
  --rollup-rpc=http://localhost:8547 \
  --l2oo-address=$(cat ../packages/contracts-bedrock/deployments/getting-started/L2OutputOracleProxy.json | jq -r .address) \
  --private-key=$GS_PROPOSER_PRIVATE_KEY \
  --l1-eth-rpc=$L1_RPC_URL
