[DOCS] An example: Create an op stack Rollup testnet with `op-deployer`

[opfocus]

Description:
I shared an article in the Create an op stack Rollup testnet with op-deployer titled Create an op stack Rollup testnet with op-deployer. My goal was to provide an example for other users to reference.

While deploying L1 contracts using op-deployer/v0.0.13, I encountered the following issue:

• _gameType is set to 1, whereas in op-mainnet and op-sepolia, this value should be 0.
• I exported the L2 configuration using the command:

  ./op-deployer inspect deploy-config --workdir .deployer "$L2_CHAIN_ID" > l2-chain-config.json

  The output shows "respectedGameType": 0, despite no modifications to the configuration. Further investigation is needed.

Since the related documentation is still being updated, users face significant challenges when creating an OP Stack Rollup testnet. I hope to see documentation updates soon and would appreciate any feedback or assistance regarding this issue in my shared article.

@opfocus This is such a nice initiative, i'll go through this and let you know my experience.
Thanks for putting this together.

@opfocus op-deployer only deploys the permissioned dispute game, game type 1. It also does it with a placeholder for the absolute prestate hash, which goes in each game type's contract. It's a circular dependency because to use the preimage and absolute prestate hash, you need the chains configuration included in there, but you can't do that until the chain has been deployed.

@krofax is working on a a document that goes into these details here: #1539

Suppose I want to have one chain deployed with permissioned fault proofs. Is there any issue that could arise from this configuration discrepancy?

[Chomtana]

Currently, docs is mixed up between an old tutorials/chain manual deployment way and the new op-deployer way make it impossible for external chain operator to follow and launch their chain.

Also I think op-deployer now default to FaultDisputeGame not L2OO?

We've observed a significantly high number of RPC calls on Alchemy when using the permissioned fault-proof system. The majority of these are eth_call requests targeting the Permissioned Dispute Game contracts — totaling approximately 13-15 million requests per day.

It appears the challenger is making these calls very frequently, which may be contributing heavily to the RPC load.

Challenger version: v1.4.0

Hi @opfocus I have a rich PR, that overhauls the old "Create an op stack Rollup testnet with op-deployer", do you mind taking a look?
