**Motivation**
When I import a file from dewiki to Wikimedia Commons, German terms in links on the file page aren't translated to English. This means that links in exported files turn to redlinks. Examples:
- `Benutzer:` should be `User:`. `Urheber=[[Benutzer:Bjs]]` should be `Author=[[User:Bjs]]`
- `Datei:` should be `File:`. `Quelle=[[:Datei:xyp.jpg]]`should be `Source=[[:File:xyp.jpg]]`.
- `Kategorie:` should be `Category:`. Changing `[[Kategorie:Datei:Ansbach]]` to `[[Category:Ansbach]]` on Commons would already work, as do most names of places. And even if categories don't exist, changing the link to `Category:`means that Commons recognizes the link as a category, and it can be changed with HotCat.
**Acceptance Criteria**
- On the most recent file page, all namespace names are recognized as such, e.g. coming as "Kategorie:...", the text is recognized as being the category namespace
