"Standard config" spec should not reference pre-fault-proofs contracts

[geoknee]

There is at least one example here:

https://github.com/ethereum-optimism/specs/blob/dfa8ea9568b0e35827be763fa8e6a2eeb9d90704/specs/protocol/configurability.md?plain=1#L55C1-L56C1

The L2OutputOracle is not used in Fault Proof systems, and standard chains must be on Fault Proofs.

I think in this case the parameter is defined off-chain in the rollup config.
