When using accessible descriptions (`aria-describedby`), ensure that the 
descriptions exist.

## Explanation

ARIA descriptions are commonly used to add supplementary information to 
elements in a page, especially form controls. For example:

```html
<input type="email" aria-describedby="email-help">
<p id="email-helpp">Enter your work email address</p>
```

In this example, the `aria-describedby` for the field points to an ID of `email-help`,
which doesn't exist. The paragraph it refers to instead has an ID of `email-helpp`, presumably 
a typo.

## Why this matters

It isn't usually clear when an accessible description is broken, even during user testing.

This check helps to identify where an element clearly intended to have a description, but
that description is missing.

When a description is broken, key information about that element may be omitted from 
assistive technologies.
