[bug] v1 Teaser Image is missing the link wrapping the image element

**Describe the bug**
v1 Teaser Image is missing the link wrapping the image element. This differs from the HTL implementation and should be normalized.

**To Reproduce**
Steps to reproduce the behavior:
1. Create a new SPA and add a v1 Teaser component
2. Author an image, title and link
3. See that there is a link around the title, but not around the image.

**Expected behavior**
The image should be wrapped in a link just like the HTL implementation

Start by locating the v1 Teaser Image rendering and comparing it with the HTL implementation, using the reproduction steps with an authored image, title, and link. Done means the image is wrapped in the link when one is authored, matching the title's behavior and the HTL implementation.
