[Console] SymfonyStyle - add string type to confirm() $question by co…

PR retargeted from Symfony 5.4: https://github.com/symfony/symfony/pull/41983

Inspired by & follow up to https://github.com/symfony/symfony/pull/41946 by `@nicolas`-grekas

<br>

This type is always string, see contract 5010ebdad9/src/Symfony/Component/Console/Style/StyleInterface.php (L102)

Also `ConfirmationQuestion` requires `string` strict type bellow

Probably forgotten during adding types everywhere in  https://github.com/symfony/symfony/pull/32318
