The link is https://www.mediawiki.org/wiki/Special:MyLanguage/Help:Content_translation/Translating/Translation_quality. When there is Special:MyLanguage in the link, version in the selected language is opened (selected language in ULS at the top right, next to the link to you user page). If there's no translation to your selected language, English is opened.
If translated version is opened, you can see language code after the title in the URL, for example Translation_quality/pt.

If Portuguese was indeed your language and you were wondering why English is shown, that is because only 2% of the content is translated to Portuguese.
