Update script.js

Script that counts from 1 to 100 and outputs the number, except in the following cases.

If a number is divisible by 3 display "Fizz" instead.
If a number is divisible by 5 display "Buzz" instead.
If a number is divisible by 3 AND 5 display "FizzBuzz" instead.
Ignore all these conditions if the number is a prime. (e.g just display the number)
