primitives: use alloy Withdrawals

[tcoratger]

Describe the feature

At the moment, we have defined a Withdrawals structure inside the primitive-traits crate:

reth/crates/primitives-traits/src/withdrawal.rs

Line 35 in eec861f

pub struct Withdrawals(Vec<Withdrawal>);

After the merge of alloy-rs/alloy#1462, this definition could be removed in reth and replaced by a simple import of the equivalent alloy type.

Seems not too hard, can I work on it? What do you think? @tcoratger

I think it could be a good first issue wdyt @mattsse? Maybe we can provide some guidance if needed :) Happy to help. This is blocked by alloy-rs/alloy#1462 at the moment

Should be unlocked by new alloy release alloy-rs/alloy@3117f76

Ready to work on this one if it is possible @mattsse.
