fix: min-content on checkbox root

[deckchairlabs]

Adding min-content as minWidth to checkbox root element prevents clipping on narrow width parents.

This totally makes sense. Are there any specific default cases you can show where this changes the result? & should we have this on Radio as well?

I've put together a codesandbox showing the result, had to hack it since the root component of both Checkbox and Radio doesn't accept any props. I'll update the PR to include the fix for the Radio component as well.

Amazing, thanks for both of those!
