Update deploy.js

[semz-ui]

Update on how to get contract address anytime a transaction is being made

[semz-ui]

Note: This is an update for etherjs 6.0^. Also, I commented out the old method on how to get the address right above the new method

Thanks. We'd need to update all dependencies as well for this... Not sure this is enough in it's current state.

contract.address will get undefined, newer version contract.getAddress() does work but making it so it will be same as outputting deploymentReceipt.contractAddress . I'm not sure is it suppose to be same?
