Feat: Add option to change boolean field color (version without toggle)

[damien-louis]

Short description of what this feature will allow to do:
When a BooleanField is used with renderAsSwitch(false), the rendering is :

<span class="badge badge-boolean-true">
    Yes
</span>

and

<span class="badge badge-boolean-false">
    No
</span>       

Yes button with blue background, No button with grey background.

It would be great to have an option to change background color (with bootstrap class for example) for a better UX (sometimes the true is a good news, sometimes a bad...

Example of how to use this feature

BooleanField::new('isDone')->renderTrue('success')->renderFalse('primary');
BooleanField::new('isBroken')->renderTrue('danger')->renderFalse('success');

Maybe it can be my first contribution if the idea is validated.
