Description

The va-radio-option component is the only component with the shadow dom open. That means that it's susceptible to outside/global style interference.

The component already has a number of style overrides related to Formation to account for this but there are a few more we need to add (see screenshots below). This PR will add those additional override styles.

Screenshots

This is an example of the issue that was provided to us:

This is the style that is getting applied to the component because the shadow dom is open. It's originating in the CSS-Library here.
