fix(javascript): call findLast in the TypedArray.findLast example

[rajanpanth]

The interactive example on TypedArray.prototype.findLast calls find() rather than findLast():

const int8 = new Int8Array([10, 0, -10, 20, -30, 40, 50]);
console.log(int8.find(isNegative));
// Expected output: -30

find() returns the first negative element, -10. The documented output -30 is the last one, which is what findLast() returns. So the example both contradicts its own stated output and demonstrates the wrong method on the page that documents findLast.

Verified in Node:

find     : -10
findLast : -30

Changing the call to findLast() makes the example produce the documented -30.

I checked the sibling pages and they are all correct: typedarray/findLastIndex, typedarray/findIndex, typedarray/find, array/findLast and array/findLastIndex each call their own method. This is the only page with the mismatch.

Found by executing every js interactive-example block under files/en-us/web/javascript that carries an // Expected output: comment and comparing the actual scalar output against the documented one: 467 blocks ran, and this was the single value mismatch.
