Misleading constant for EIP-2935

[0xMushow]

Fixing misleading constant for EIP-2735 that's only used for testing in protocol_params.go.

go-ethereum/params/protocol_params.go

Line 183 in a9a19c4

HistoryServeWindow = 8192 // Number of blocks to serve historical block hashes for, EIP-2935.

This should be set to 8191. This constant is used in for verkle testing.

go-ethereum/core/verkle_witness_test.go

Lines 270 to 279 in a9a19c4

	// getContractStoredBlockHash is a utility method which reads the stored parent blockhash for block 'number'
	func getContractStoredBlockHash(statedb *state.StateDB, number uint64, isVerkle bool) common.Hash {
	ringIndex := number % params.HistoryServeWindow
	var key common.Hash
	binary.BigEndian.PutUint64(key[24:], ringIndex)
	if isVerkle {
	return statedb.GetState(params.HistoryStorageAddress, key)
	}
	return statedb.GetState(params.HistoryStorageAddress, key)
	}

This isn't used in the EIP-2735 implementation checks, because it uses the following bytecode, that indeed uses 0x1FFF here (8191)

go-ethereum/params/protocol_params.go

Line 213 in a9a19c4

HistoryStorageCode = common.FromHex("3373fffffffffffffffffffffffffffffffffffffffe14604657602036036042575f35600143038111604257611fff81430311604257611fff9006545f5260205ff35b5f5ffd5b5f35611fff60014303065500")

It was misleading when I was double checking this implementation.
