fix(aggregation_mode): invert variables order and add setter for Risc0 contract

[JuArce]

Description

Variable declaration in AlignedProofAggregation contract was

    /// @notice The address of the SP1 verifier contract.
    /// @dev This can either be a specific SP1Verifier for a specific version, or the
    ///      SP1VerifierGateway which can be used to verify proofs for any version of SP1.
    ///      For the list of supported verifiers on each chain, see:
    ///      https://docs.succinct.xyz/onchain-verification/contract-addresses
    address public sp1VerifierAddress;

    /// @notice The address of the Wallet that is allowed to call the verify function.
    address public alignedAggregatorAddress;

In PR #1874, it was changed to

    /// @notice The address of the SP1 verifier contract.
    /// @dev This can either be a specific SP1Verifier for a specific version, or the
    ///      SP1VerifierGateway which can be used to verify proofs for any version of SP1.
    ///      For the list of supported verifiers on each chain, see:
    ///      https://docs.succinct.xyz/onchain-verification/contract-addresses
    address public sp1VerifierAddress;

    /// @notice The address of the Risc0 verifier contract
    /// @dev See supported verifier here:
    /// https://dev.risczero.com/api/blockchain-integration/contracts/verifier#contract-addresses
    address public risc0VerifierAddress;

    /// @notice The address of the Wallet that is allowed to call the verify function.
    address public alignedAggregatorAddress;

Causing to set risc0VerifierAddress to alignedAggregatorAddress, and set alignedAggregatorAddress to 0x0...0
