Enforce recommended Gridicon size attributes

Gridicon JSX elements must use one of the recommended sizes.

In previous incarnations, this warning could be subdued by adding a nonStandardSize prop to the element, but it's recommended instead to disable the rule using standard ESLint rule options (documentation).

Rule Details

The following patterns are considered warnings:

<Gridicon size={ 20 } />;

The following patterns are not warnings:

<Gridicon size={ 18 } />;
