fix(#patch); aave-v3-forks; fix liquidation protocol fee calculation

[dhruv-chauhan]

// Earlier, 

liquidationProtocolFee = liquidationPenalty * liquidationProtocolFeePercentage * liquidatedCollateralAmount / (1 + liquidationPenalty - liquidationPenalty*liquidationProtocolFeePercentage)

// Changed,
// From the BalanceTransfer events sent on LiquidationCall https://github.com/aave/aave-v3-core/blob/724a9ef43adf139437ba87dcbab63462394d4601/contracts/protocol/tokenization/AToken.sol#L117

liquidationProtocolFee = balanceTransfer.value * (balanceTransfer.param_index / 10^27)

lgtm, we will also have to apply this to aave v2 as well. I am cutting you a ticket for that, and you can do it in a new PR
