feat: update nonce to return managed nonce for contract accounts

[ftupas]

Feature Request

Describe the Feature Request

Currently, we return the protocol-level nonce both for EOA and Contract Accounts

kakarot-rpc/crates/core/src/client/mod.rs

Lines 318 to 333 in 50fc732

	async fn nonce(&self, ethereum_address: Address, block_id: BlockId) -> Result<U256, EthApiError<P::Error>> {
	let starknet_block_id: StarknetBlockId = EthBlockId::new(block_id).try_into()?;
	let starknet_address = self.compute_starknet_address(ethereum_address, &starknet_block_id).await?;
	self.starknet_provider
	.get_nonce(starknet_block_id, starknet_address)
	.await
	.map(|nonce| {
	let nonce: Felt252Wrapper = nonce.into();
	nonce.into()
	})
	.or_else(|err| match err {
	ProviderError::StarknetError(StarknetError::ContractNotFound) => Ok(U256::from(0)),
	_ => Err(EthApiError::from(err)),
	})
	}

Describe Preferred Solution

When this pr is merged, we need to do the following:

• update nonce so that for EOA we take the native nonce and for Contract Accounts, the managed nonce
• add tests for the new nonce logic
