fixed typo, change presentation of quote
This MR:
- Corrects the typo in the leading question "How Is Okular Sustainable?"
- Corrects text for the quote
- Adds hyperlink to the taz article
- Adjusts margins around the quote
- Puts English translation in italics and original German in smaller font with quotation marks
Minor open issues not fixed here:
- There is significant space between paragraphs 3 and 4 which I do not know how to adjust.
- Also, I think it would look better to have a bit of space in the left margin of the quote, which again I do not know how to adjust.
