Use json_validate in Rules\Json if available (#1394)
[`json_validate` function](https://wiki.php.net/rfc/json_validate)
[added in PHP 8.3](https://php.watch/versions/8.3/json_validate) validates a
given string input to contain valid JSON without decoding it in memory.

This adds a function availability check to `Rules\Json`, and uses the new
function instead of decoding the given input, followed by a last-error check.
