add a new accordion element on the front page

[Majapur1]

New element on the front page

• add an accordion element with an information about the project with a function to parsing markdown from de.json (that helps to avoid a huge amount of lines in de.json for just one markdowned description);
• update of de.json file;
• add some extra additional colors into tailwind.config.ts.

thanks @Majapur1 - as we just discussed, I'd suggest that for now

• you directly put the HTML in de.json
• and remove the parseMarkdown function
  I'll look into Allow some formatting in translations #210 and Allow admins to edit the german translations #211 to follow up on this
