Score circle not changing colours

Problem/Motivation

The Yoast SEO circle is changing coller by a class which is added to the div around it.

However, the CSS is defined as:

.overallScore.good

While the class is being added as

class="overallScore Good"

Because of the capital G the CSS is not being applied.

Steps to reproduce

Reach a ranking that should change the score (good, ok, bad).

Proposed resolution

Fix the class adding logic to be lowercase.
