"maxFeePerGas" may be lower than maxPriorityFeePerGas

[oleksandrSydorenkoJ]

Describe the bug
Skale uses maxFeePerGas as a gasPrice for type0,1 transactions.
maxPriorityFeePerGas doesn't use anywhere within the skaled functionality
But, eip 1559 provides the formula
maxFeePerGas = baseFeePerGas + maxPriorityFeePerGas
Where maxFeePerGas cannot be lower than maxPriorityFeePerGas.

Versions
skalenetwork/schain:3.19.2-beta.0

Preconditions
Active schain medium type

To Reproduce

1. Send type2 transaction with transaction params:

    transaction_type2_data = {
        'maxPriorityFeePerGas': 300000,
        'maxFeePerGas': 100000,
        'gas': 100000,
        'chainId': web3.eth.chain_id,
        'type': 2
    }

2. Check transaction by hash

Expected behavior
Skaled should return the error

E           ValueError: {'code': -32000, 'message': 'max priority fee per gas higher than max fee per gas'}

Actual state
Skaled sends the transaction and receives the transaction by hash without any errors.
