richtext-lexical editor.

**Before:**

**After:**

![after](https://github.com/user-attachments/assets/1c4af50e-2216-4ada-aff0-7a5e5559ac64)


### Why?

As described in #6867, the thumbnail in the richtext-lexical editor is
always trying to render an thumbnail image. This leads to a broken image
as soon as a non-image is added.

### How?

The fix was done by using the `<Thumbnail />` component from
`@payloadcms/ui`

Fixes #6867
