Fix Proxy examples

[leobalter]

the [[Get]] internal slot of Proxy calls the handler with target, P, and receiver as arguments.

the [[Call]] internal slot [calls the handler] with thisArgument and an argsList which is an Array made from the argumentsList. You don't need to use a rest parameter there.

What about keeping "name", but change the parameters? Maybe use a different example that clarifies the use of this. For example:

var person = { name: "Alice" };
var handlers = {
    get: function (target, property, receiver) {
        if (property === "realName") {
            return target.name;
        } else if (property === "fakeName") {
            return "Really " + receiver.name;
        }
        return "Bob";
    }
};

var fakePerson = new Proxy(person, handlers);
fakePerson.name === "Bob" &&
fakePerson.realName === "Alice" &&
fakePerson.fakeName === "Really Bob";
