Fix minor syntax error in type hash (#75)

* fix: minor syntax error in Request's typeHash located at naive-receiver/BasicForwarder.sol

This commit fixes an issue in the _REQUEST_TYPEHASH definition within the BasicForwarder contract by adding a missing closing parenthesis in the typeHash string.
This error was non-compliant with the EIP-712 standard and could result in the rejection of legitimate requests.
