Fix PHPDoc type annotation for validateInteger parameters

This PR fixes a PHPStan error caused by the PHPDoc type annotation added in #56503 for the validateInteger() method's $parameters argument.

Problem

The PHPDoc type array{0: 'strict'} requires the first element to always be present and be the string 'strict'. However, the $parameters argument defaults to an empty array [], which causes a PHPStan type mismatch error when the method is called without the strict option.

/**
 * @param  array{0: 'strict'}  $parameters  // ❌ Requires element 0 to exist
 */
public function validateInteger($attribute, $value, array $parameters = [])
{
    if (($parameters[0] ?? null) === 'strict') {
        return is_int($value);
    }
    return filter_var($value, FILTER_VALIDATE_INT) !== false;
}

Solution

Changed the PHPDoc type to array<int, string> to properly reflect that:

• The array can be empty (default case)
• When provided, it contains string values at integer keys
• This aligns with other validation rule parameter types in the codebase

/**
 * @param  array<int, string>  $parameters  // ✅ Allows empty array
 */

Benefits

• Eliminates PHPStan errors for projects using strict type checking
• Maintains backward compatibility with existing code
• Consistent with parameter type definitions in other validation methods

@shaedrich
Thank you for the feedback! I've updated it to array{0?: 'strict'}.

I initially used array<int, string> to match the pattern used in other validation methods in the class, but I agree that the more specific type is better here.

Thanks a lot!
