Line Numbers in Code Blocks

How can I configure to not show the line numbers for my code blocks?

```js
posts: [
{
id: 1,
title: 'This is my first post',
body: 'Some description would go here'
}
]
```

When I view the page I see this


I opened a ticket with ember-prism, thinking maybe that comes from them, but they say on theirs the default is no line numbers

Start by checking the addon's integration with ember-prism, which the issue identifies as the source of the code-block behavior. Confirm where line numbers are enabled and whether the existing configuration can disable them; done when the shown fenced JavaScript block renders without line numbers.
