this removes the distinction between remove and prune, and fixes the bug if TransactionPool::remove_transaction is called manually, which we currently only do in auto-seal

reth/crates/transaction-pool/src/traits.rs

Lines 270 to 277 in c2b7a38

	/// Removes all transactions corresponding to the given hashes.
	///
	/// Also removes all _dependent_ transactions.
	///
	/// Consumer: Block production
	fn remove_transactions(
	&self,
	hashes: Vec<TxHash>,

This isn't correct now, and I think we should change this to adhere to the docs?

now we're advancing the independent tx on remove
this does not affect how we remove mined transactions
and also does not affect how we discard txs because we remove all descendant txs there

lgtm, yeah the trait docs should be updated
