RadioGroup allow supporting prop to be able to use ReactNode

[liywjl]

Is your feature request related to a problem? Please describe.

In some quizzes on frontend we have a supporting image next to the question (example: https://www.theguardian.com/football/that-1980s-sports-blog/2020/jun/12/sports-quiz-football-in-the-1980s look at question 4).

The best way to render the supporting image would be as part of the RadioGroup component. However there is no way to have text followed by supporting media in the current design.

Describe the solution you'd like

We could change supporting prop on RadioGroup to allow text | ReactNode allowing us to have images or videos as supporting content.

Describe alternatives you've considered

• We could add another prop (suggestion: supportingMedia as a name) to RadioGroup
• We could allow RadioGroup to allows other components other than Radio (not ideal)
