Javascript-exercises: 02_repeatString - Fix code on line 32

The original code had "hey" as the seed string value and hence the comment on line-29 mentions "hey". But the last commit on the code changed "hey" to "odin".

We can either change instances of comment or the code. I propose changing the code instance from "odin" to "hey" for consistency.
