Fix rlp: expected List error for legacy Arbitrum receipt encoding

Update go-ethereum submodule with fix for ReadCanonicalRawReceipt
failing on blocks with Arbitrum legacy receipt encoding.

When NewListIterator or extractReceiptFields fails on legacy formats,
fall back to ReadRawReceipts which handles both modern and legacy
receipt formats via ReceiptForStorage.DecodeRLP.
