- add anker links (done)
- add images (the correct path is missing)

(the change of: [[!img install/inc/screenshots/desktop.png link="no" alt="Tails desktop"]], I do not know why it is there. I did not intend to change it)

(cherry picked from commit cb943701)

So for the moment I upload it into here. 

What? favicons

drop /en

The previous link was broken for at least 2 different reasons.

While I'm at it:

 - switch this link to using the tails_gitlab ikiwiki shortcut
 - make the URL filter the labels it's about

Previously it linked to Starter issues in the tails/tails project,
but we have a few Starter issues in other tails/* projects.

Somehow I managed to mistype the name of the Starter label.

Let's link to the code that resulted from resolving these issues.

That was fixed years ago.

Fixes regression introduced in ca006f09.
