do not translate anchors
Currently, anchors are translated/localized along with the contents e.g. in our docs, like with
https://f-droid.org/docs/All_About_Descriptions_Graphics_and_Screenshots/#datenformat
This probably happens because the TOC generator generates them based on the header titles. But if one shares such a link, it won't work properly when visited by somebody using a different locale.
As discussed in today's meeting, a possible solution would be to write a custom TOC generator.
