blocked until contracts are deployed in Arbitrum Mainnet

Suggested change: I think we should use arbitrum-one-mainnet as the name of the network to follow the arbitrum-one-* naming convention that we already use for arbitrum-one-rinkeby since "Arbitrum One" is the term used to distinguish Arbitrum's flagship rollup chain from other deployments of Arbitrum rollup chains.

Making a note that we'll want to remember to set redeemGas in the network config for arbitrum-one-mainnet similar to what we do for arbitrum-one-rinkeby in #2252
