chore: fix type cast in `ResetPasswordRequestRepositoryTrait` when using `declare(strict_types=1);`

When using `declare(strict_types=1);` in `ResetPasswordRequestRepositoryTrait`, an error occurs on the token generation because the `getSingleIdentifierValue` method returns a scalar value (in my case an integer because I'm using auto-incremented integers) instead of a string as required by the method.
