[Feature] Add --version command to built binary

[dylanschultzie]

🚀 Feature

Add --version to snarkos such that we can see what tag and git commit hash was used to build the binary.

Other networks version:

near:

$ neard -V
neard (release 2.3.1) (build 2.3.1) (rustc 1.81.0) (protocol 72) (db 40)
features: [default, json_rpc, rosetta_rpc]

solana:

$ solana --version
solana-cli 1.18.25 (src:92ddaa20; feat:3241752014, client:Agave)

cosmoshub:

$ gaiad version
release/v21.x-7c0c4cbb7b26c48b235f60532223a74f4f68b830

Motivation

This helps debug issues with builds to ensure binary is correct (doing sha256sum snarkos, as an example, isn't a good stand-in). It also helps automations to confirm the new build is the correct output.

Implementation

Are you willing to open a pull request? (See CONTRIBUTING)

+1 please. Our automated build verification process would very much appreciate this feature.

I think this is a very necessary feature as we need to check the version of the built binary.
