[Feature] Add network-parameterized block responses

[onbjerg]

Component

network, json-rpc, providers, pubsub

Describe the feature you would like

#190 replaced the provider with a network-parameterized provider, but block responses are still just Ethereum headers and Ethereum transactions. We need a Block type generic for networks.

We have one in alloy-network but we need to check that it is correct and use it in alloy-providers:

alloy/crates/network/src/lib.rs

Lines 36 to 51 in 63af0c4

	pub enum TransactionList<T> {
	/// Hashes only.
	Hashes(Vec<B256>),
	/// Hydrated tx objects.
	Hydrated(Vec<T>),
	/// Special case for uncle response
	Uncled,
	}
	/// A block response
	#[derive(serde::Serialize, serde::Deserialize, Debug, Clone)]
	pub struct BlockResponse<N: Network> {
	#[serde(flatten)]
	header: N::HeaderResponse,
	transactions: TransactionList<N::TransactionResponse>,
	}

Additional context

No response

#383 follow up: Remove the lines below and wrap Block in WithOtherFields<Block> instead

alloy/crates/rpc-types/src/eth/block.rs

Lines 962 to 963 in 28cab90

	#[serde(flatten)]
	pub extra_info: BTreeMap<String, serde_json::Value>,

Btw I would like to take this on once #383 is merged.
