Webdriver: Forward ErrorStatus for take element screenshot (#38134)

Based on
[spec](tests/wpt/meta/webdriver/tests/classic/take_element_screenshot/screenshot.py.ini),
we should not expect the error to only be
`ErrorStatus::StaleElementReference`.

Testing:
`tests/wpt/meta/webdriver/tests/classic/take_element_screenshot/screenshot.py.ini`
