Fees are too low, transaction to retrieve them costs more than the earnings
Description
The protocol asks for 1e9 fees per claim, which lead at most at 4 Gwei if all users claim their airdrop before the claimFees function is called. However price of the transaction on ZkSync will be higher. The price per used gas is 0.025 gwei on ZkSync (recently this has been a pretty constant number) and the function will consume about 8700 gas according to Foundry. So, the transaction will cost about 217 Gwei, which is 57 times larger than the collected fees.
