Recommendations should be phrased as actions

Here's an example of a recommendation generated by Lighthouse's accessibility tests:

> Link text (and alternate text for images, when used as links) that is discernible, unique, and focusable improves the navigation experience for screen reader users. [Learn more](https://web.dev/link-name/).

Instead, recommendations should always be phrased as such:

> Update your links' content to ensure they all contain text for screen reader users.

One idea would be to map out all of the possible recommendations from Lighthouse's accessibility test, and to rephrase the recommendations for each type.
