Checkbox/Radio - allow flow content as body

Is this a new component or an extension of an existing one?

Existing components, Checkbox and Radio.

Describe the feature

To allow flow content for their body prop. Currently it's wrapped in a span element, which only admits phrasing content.

Are there visuals for this feature? If applicable, please include examples for each state and for varying widths

I don't think so.

Any other information?

• The body being wrapped in a span was requested in a review because the Radio isLabelWrapped prop. See https://github.com/patternfly/patternfly-react/pull/5559#pullrequestreview-617903386

• I've created a silly weird example of a Checkbox using flow content in its body, just for illustrating a possible use case of a React node returning a div. See https://codesandbox.io/s/weird-patternfly-checkbox-91mzqq or the screenshot uploaded below

• If the change isn't possible beacuse the benefit does not pay off complicating the code for these components, at least it would be nice to mention in the documentation that the expected React.ReactNode must return phrasing content only

Inizia con i componenti Checkbox e Radio e verifica come viene racchiusa la loro prop body, incluso il comportamento isLabelWrapped menzionato nell’issue. Determina se è possibile supportare flow content senza compromettere il comportamento esistente di label; il lavoro è completo quando entrambi i componenti accettano il contenuto previsto oppure la documentazione di Checkbox dichiara chiaramente che il contenuto di body deve essere phrasing content.
