instructions:----------
For this question, we will be working with a subclass of Jeroo called CountingJeroo that tracks the number of hops it has peformed.
You can get the number of hops performed so far by calling the `getHopCount()` method.
Below is a while loop with using a Jeroo named `imani`.
Currently, this loop will cause the jeroo to hop 10 times.
Change the conditon so that the jeroo will only hop five times instead.
