feat: show contract's code_hash upon deployment

[brunopgalvao]

When working with contracts, it is often useful to have the contract's code_hash.

Ask: Have pop up contract also output the contract's code_hash.

Currently, when I deploy the contract using the pop up contract command, the contract's account id is outputted but not the code_hash and depending on my development flow, I need to go to PolkadotJs Apps and look up the contract's code_hash based on the contract's account id.

Here is the output that cargo-contract gives (having the events is nice too):

cargo-contract contract upload --suri //Alice -x

As an ancillary feature: it would be nice to have a pop command to return a contract's info (e.g. code_hash) based on a contract’s account id e.g.:

// Returns contract info including code_hash
pop info contract 5DTZ3vQjvm77YsfcgB1z5JoJFtkw4SLZDVXx9Pdd1wziQYoD

cargo-contract has this command:

cargo-contract contract info --contract 5GbGt9yBUmb58u7XBbhf6uDtRETd9MjKQrbDWT4mzy1RmhGb
