[13.x] Add #[\Override] to the BatchFake class methods

[imanghafoori1]

Marks the overridden methods with the proper PHP attribute.

illuminate/support doesn't require symfony/polyfill-php83 and this would cause an issue using the component outside of Laravel Framework on PHP 8.2

We selectively use #[\Override] on components that rely on external packages such as Symfony to handle breaking changes

[crynobone]

Might be best to have this for master branch where we bump the minimum PHP versions to 8.3

@crynobone Thanks for the clarification. The PR is now from master to master branch
