Fix JavaScript hello world example

[acangiano]

Description

The current Snippet Note Example's JavaScript file references a non-existent element with id enjoy. The HTML file has an element with id hello. I updated the JavaScript file to reference the same id (i.e., hello).

I know that the HTML file doesn't include the JavaScript file, so the two could be considered independent, but I think it's less confusing to keep IDs consistent.
