contracts-bedrock: weth predeploy version (ethereum-optimism#10441)

Updates the weth predeploy to be versioned.
Even though the weth predeploy is not proxied, adding
a version safely lets us make small modifications to it in the
future such as updating the version of `solc` that is used
to compile it and be able to be aware offchain of the version
that the chain has without needing to keep a registry of codehashes.
