driver.findElement() and element.findElement() must throw NoSuchElementException if element is not found.

[BorisOsipov]

    @Test
    public void notExistShouldThrowNoSuchElementException() {
        var driver = new PlaywrightiumDriver();
        final String url = "https://testpages.eviltester.com/styled/basic-html-form-test.html";
        driver.get(url);
        WebElement element = driver.findElement(By.name("#not-existing"));
    }

This test must fail, but it passes.
