New Infura networks missing from BUILT_IN_NETWORKS constant

Medium Severity

The four new Infura networks (avalanche-mainnet, monad-mainnet, hyperevm-mainnet, megaeth-mainnet) are added to InfuraNetworkType, BuiltInNetworkName, ChainId, NetworksTicker, BlockExplorerUrl, and NetworkNickname, but are not added to the BUILT_IN_NETWORKS constant in constants.ts. Every previous network addition also updated BUILT_IN_NETWORKS. This exported object is used by consumers and test helpers (e.g., BUILT_IN_NETWORKS[infuraNetwork].chainId) to look up network metadata — accessing the new networks there will return undefined and cause runtime errors.

Will need to investigate more. Original idea was just to add networks into InfuraNetworkType but then other objects depended on it. I don't want to risk a regression and so I'll have to audit it
