Outdated Doc Detector

There are several developer websites that support multiple languages which are translated from English. Non-English developers prefer to use their native language as the default display language. But these non-English documents on the website maybe out of date compared with it's corresponding English versions. *Outdated documents often lead to potential problems and are inconspicuous for developers.* This extension is used to indicate whether the document is out of date by comparing the updated time between non-English version and English version of the same page. It will show a warning bar on the top of the website and show different icons on the address bar if the content is non-English and outdated. Currently the supported developer websites include MDN Web Docs, Android Developers, Google Developers, Firebase Developers, Google Cloud Developers and TensorFlow Developers.
