Add create2 deployment example

[alxiong]

I saw that there's create2 related api for contract address computation, but no full example on deploying contracts (with alloy generated bindings using CREATE2 at a predetermined address given a numeric and a address.

(Is it through MyContract.deploy_builder().xxx()? or configuring TransactionRequest::new().xxx()? I wasn't able to figure out by searching through the docs, need guidance here)
