refactor: use ZEND_PARSE_PARAMETERS_NONE() (#14442)

Prefer:

	ZEND_PARSE_PARAMETERS_NONE();

Over:

	if (zend_parse_parameters_none() == FAILURE) {
		RETURN_THROWS();
	}

It's shorter, more modern, and they do the same thing. Technically,
ZEND_PARSE_PARAMETERS_NONE doesn't check that there's an exception,
but it generates one, so it's still cohesive.
