Teasers are no longer `<a>` tags

[jackahl]

Description

Teaser Blocks are for some don't act as usual <a> tag links anymore but handle the linking via js. This has the effect that you can no longer open the links in a new tab, copy the link address or see the browser tooltip with the link address. IMHO this is not an acceptable behaviour, both for overall usability and accessibility. I don't see any reason why we would want that behaviour.

Steps to reproduce

1. got to https://light-theme.kitconcept.io/
2. right-klick on any teaser there
   --> no option to open in new tab
3. klick on "inspect"
   --> the teaser is not wrapped in an <a>-tag
