[Feature] enabling rand feature for re-exported ruint crate

[cool-mestorf]

Component

primitives

Describe the feature you would like

using alloy-primitives with rand feature enabled does not enable re-exported ruint::Uint type's rand related trait implementation.

# Cargo.toml
[dependencies]
alloy-primitives = {version="0.4.2", features=["rand"]}
rand = "0.8.5"

// main.rs
use alloy_primitives::U256;
use rand::{thread_rng, Rng};

fn main() {
    let mut rng = thread_rng();
    let u: U256 = rng.gen();
    println!("{}", u);
}

error[E0277]: the trait bound `Standard: Distribution<Uint<256, 4>>` is not satisfied
  --> src/main.rs:6:23
   |
6  |     let u: U256 = rng.gen();
   |                       ^^^ the trait `Distribution<Uint<256, 4>>` is not implemented for `Standard`
   |

I expect a single line fix can solve this issue:
