feat(l1): properly format client version

[mechanix97]

Motivation

The client version was hardcoded in the rpc crate

It was used in the client RPC msg, in the admin_info RPC msg and in the helloMsg in P2P

Description

Added vergen crate to include more environment variables at build time in the ethrex main package.

It can be tested using the following cast commands

 cast client --rpc-url localhost:8545
 cast rpc admin_nodeInfo --rpc-url http://localhost:8545

Modified the P2PContext struct to include the client_info
Also added it in the struct RLPxConnection to pass it to the helloMessage struct when doing the handshake

Modified the test to use the functions with a dummy client_info

The version can now be retrieved by using ethrex --version

Closes #2548

Shouldn't we also update this in the p2p HelloMessage exchange, see here.

This looks good, but Im not convinced we should add this to the common crate. I think it should be in the p2p crate probably, and there should be a way for the rpc crate to ask this info from the p2p crate. This requires a bigger refactor which is out of scope of this PR. Let's think about it for a minute and then we can go back to this.

Looking good so far, left some comments
