Add create2 deployment example

I saw that there's [`create2` related api ](https://docs.rs/alloy/latest/alloy/primitives/struct.Address.html#method.create2) 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)
