feat(pops): Flag Tests for the Challenger

feat(pops): Dispute Game Contract Interfaces

fix(ctb): Remove unused mainnet artifact

feat(pops): Clobbered pops/dispute-game-contracts, seaport-style

fix(op-proposer): Missing CheckRequired Invocation

Add Base Goerli chain ID and addresses to JS SDK

ci: Increase timeout for op-program verifying goerli.

ci: Exclude explorer.optimism.io from link checker.

It regularly rejects requests from CI due to DoS prevention even though the link is valid.

Needs extra time when the batcher is delayed getting data on-chain.

feat(pops): Refactor Challenger for Testability

feat(sdk): Add a bedrock warning

This looks for all environment variables with a prefix like OP_NODE
and then validates them against the list of environment variables
provided by the flags for the component. It is not a critical error
to provide an unused environment error, but we do log at a warn level
to suggest to users that the value is not taking an effect.
