Add code comments for compatible Contracts versions

[ericglau]

Fixes #293
Fixes #319

Adds code comments for compatible Contracts versions, and Cairo lang version for Cairo. See preview here.

Solidity example:

// SPDX-License-Identifier: MIT
// Compatible with OpenZeppelin Contracts ^5.0.0
pragma solidity ^0.8.20;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";
...

Cairo example:

// SPDX-License-Identifier: MIT
// Compatible with OpenZeppelin Contracts for Cairo ^0.9.0
// Cairo lang 2.5.3

#[starknet::contract]
mod MyToken {
    use openzeppelin::token::erc20::ERC20Component;
...

Note that in both cases, the import or use statements link to the latest versions of the libraries rather than the minimum compatible version.
