Wrong require in Cairo example

[fontanellag]

Within the example in https://github.com/crytic/building-secure-contracts/tree/master/not-so-smart-contracts/cairo/unchecked_from_address_in_l1_handler the require in setOwnerOnL2() should be:

 require(OWNER == msg.sender, "not owner");

instead of

 require(owner == msg.sender, "not owner");
