[fix] yandex engine: capture captcha from header instead of url path (#5417)
Yandex engine will return parsing error instead of informing that a CAPTCHA was found. It is confusing for the admin and the users (#5415).


This patch fixes an issue where the CAPTCHA response from Yandex wouldn't be detected, resulting in `ParserError` when trying to parse the response to DOM.

In this fix, I replaced the url condition and instead is checking if the `x-yandex-captcha` header is set, and is equal to `captcha`.

Alternatively, maybe something like `resp.headers.get('Location', '').startswith("https://yandex.com/showcaptcha")` could be done instead. Lastly, setting `params['allow_redirects'] = True` can also work, but this will waste an extra request. Just let me know.
