Booleans in Radio groups

• This is not a v0.x issue.
• I have searched the issues of this repository and believe that this is not a duplicate.

Expected Behavior

Since 3.2.1 Radio elements can have a boolean value. Great! Have been waiting for this functionality for a while. Tested it immediately and found some issues:

1. FormControlLabel should support numbers & booleans now as well. This gives a warning now.

<FormControlLabel
    value={false}
    control={<Radio />}
    label="green"
/>

1. When using the boolean values, the value in onChange function of RadioGroup gets transformed to String anyway.

@karensg The idea behind #13173 was to allow people have the native input do the type casting to a string. We try not to be opinionated around how the native input behaves. Another way to see it, is that we trust React for having picked the best tradeoff. I can easily imagine the behavior you are looking for being rolled out to all React users. Thanks for raising the concern.

I struggled a bit with React Hook Form + Zod, since I wanted to manage booleans in my business logic, but the templating was messing with strings.

Don’t know if it can help but here my “workaround”: https://stackoverflow.com/a/74854174/3608410
