[PHP 8.3] Replace Json::isValid() implementation with new json_validate()

[aedart]

Description

From PHP 8.3, a new json_validate can be used to determine if a string is valid json or not. This can allow us replace the current implementation of Aedart\Utils\Json::isValid().

Flags

The new json_validate also accepts depth and flags arguments. This means that the Json::isValid() method also must accept those arguments and the method signature must therefore be expanded, e.g.

    public static function isValid(mixed $value, int $depth = 512, int $options = 0): bool
    {
        if (!is_string($value)) {
            return false;
        }

        return json_validate($value, $depth, $options);
    }

Additional

json_validate() uses less memory than json_decode, which means that one could improve performance handling decoding errors, in the Json::decode() method. See article for details.

Also, perhaps we should also consider method for obtaining the last error...

[aedart]

This feature can, at its earliest, be added from major version 8.0 of Athenaeum, where the PHP support will be 8.2 - 8.3

[aedart]

For now, the current implementation of isValid() should be good enough. Once PHP 8.3 is set as the minimum required version, then the native function should be used.
