optimism: OP Stack getting started guide is broken

The OP Stack guide for deploying a Bedrock optimistic roll-up gets stuck during L1 contract deployment. Specifically, the initializing transactions do not go through.

To Reproduce Precisely follow the guide at https://stack.optimism.io/docs/build/getting-started/#deploy-the-l1-contracts

Deployment gets stuck around step 19, initialize SystemDictator

Running the script for the first time gets stuck after all contracts are deployed + one more transaction (upgradeToAndCall). Logs attached, “appendix 1”. Subsequent runs of the script get stuck on the next transaction (changeAdmin). Logs attached, “appendix 2”.

Reproducibility Looking on-chain, there seem to be several people who tried deploying the OP Stack and got stuck on the same step. Notice how all these addresses get stuck trying to call changeAdmin over and over. this person, 8 days ago this person, 5 days ago this person, 1 day ago
