Description

The current code in ValidationRuleParser explodeExplicitRule function does not handles the explode for multiple chained non-nested Date or Numeric Rule objects. It falls into the condtion that checks if the rule is an object and wraps the rule in an array as a string cast without exploding it at the pipe symbol.

protected function explodeExplicitRule($rule, $attribute)
    {
        if (is_string($rule)) {
            return explode('|', $rule);
        }

        if (is_object($rule)) {
            // The bug lies here, prepareRule falls to a return of (string) $rule
            return Arr::wrap($this->prepareRule($rule, $attribute));
        }

        $rules = [];

        foreach ($rule as $value) {
            if ($value instanceof Date || $value instanceof Numeric) {
                $rules = array_merge($rules, explode('|', (string) $value));
            } else {
                $rules[] = $this->prepareRule($value, $attribute);
            }
        }

        return $rules;
    }

Steps To Reproduce

A simple validation like the following is failing

$rules = [
    'date' => Rule::date()->format('Y-m-d'),
];
